## 数学代写|随机图论代写Random Graph代考|Generalized Random Intersection Graphs

Godehardt and Jaworski [ 389 ] introduced a model which generalizes both the binomial and uniform models of random intersection graphs. Let $P$ be a probability measure on the set ${0,1,2, \ldots, m}$. Let $V={1,2, \ldots, n}$ be the vertex set. Let $M=$ ${1,2, \ldots, m}$ be the set of attributes. Let $S_1, S_7, \ldots, S_n$ be independent random subsets of $M$ such that for any $v \in V$ and $S \subseteq M$ we have $\mathbb{P}\left(S_v=S\right)=P(|S|) /\left(\begin{array}{l}m \ |S|\end{array}\right)$. If we put an edge between any pair of vertices $i$ and $j$ when $S_i \cap S_j \neq \emptyset$, then we denote such a random intersection graph as $G(n, m, P)$, while if the edge is inserted if $\left|S_i \cap S_i\right| \geq s, s \geq 1$, the respective graph is denoted as $G_s(n, m, P)$. Bloznelis [99] extends these definitions to random intersection digraphs.
The study of the degree distribution of a typical vertex of $G(n, m, P)$ is given in [464], [242] and [97], see also [465]. Bloznelis ( see [98] and [100]) shows that the order of the largest component $L_1$ of $G(n, m, P)$ is asymptotically equal to $n \rho$, where $\rho$ denotes the non-extinction probability of a related multi-type Poisson branching process. Kurauskas and Bloznelis [541] study the asymptotic order of the clique number of the sparse random intersection graph $G_s(n, m, P)$.
Finally, a dynamic approach to random intersection graphs is studied by Barbour and Reinert [63], Bloznelis and Karoński [107], Bloznelis and Goetze [104] and Britton, Deijfen, Lageras and Lindholm [166].
One should also notice that some of the results on the connectivity of random intersection graphs can be derived from the corresponding results for random hyperghraphs, see for example [519], [707] and [390].

McDiarmid and Müller [588] gives the leading constant for the chromatic number when the average degree is $\Theta(\log n)$. The paper also shows a “surprising” phase change for the relation between $\chi$ and $\omega$. Also the paper extends the setting to arbitrary dimensions. Müller [618] proves a two-point concentration for the clique number and chromatic number when $n r^2=o(\log n)$.
Blackwell, Edmonson-Jones and Jordan [96] studied the spectral properties of the adjacency matrix of a random geometric graph (RGG). Rai [672] studied the spectral measure of the transition matrix of a simple random walk. Preciado and Jadbabaie [665] studied the spectrum of RGG’s in the context of the spreading of viruses.
Sharp thresholds for monotone properties of RGG’s were shown by McColm [582] in the case $d=1$ viz. a graph defined by the intersection of random subintervals. And for all $d \geq 1$ by Goel, Rai and Krishnamachari [391].
First order expressible properties of random points
$\mathscr{X}=\left{X_1, X_2, \ldots, X_n\right}$ on a unit circle were studied by McColm [581]. The graph has vertex set $\mathscr{X}$ and vertices are joined by an edge if and only if their angular distance is less than some parameter $d$. He showed among other things that for each fixed $d$, the set of a.s. FO sentences in this model is a complete noncategorical theory. McColm’s results were anticipated in a more precise paper [388] by Godehardt and Jaworski, where the case $d=1$, i.e., the evolution a random interval graph, was studied.
Diaz, Penrose, Petit and Serna [256] study the approximability of several layout problems on a family of RGG’s. The layout problems that they consider are bandwidth, minimum linear arrangement, minimum cut width, minimum sum cut, vertex separation, and edge bisection. Diaz, Grandoni and Marchetti-Spaccemela [255] derive a constant expected approximation algorithm for the $\beta$-balanced cut problem on random geometric graphs: find an edge cut of minimum size whose two sides contain at least $\beta n$ vertices each.
Bradonjić, Elsässer, Friedrich, Sauerwald and Stauffer [162] studied the broadcast time of RGG’s. They study a regime where there is likely to be a single giant component and show that w.h.p. their broadcast algorithm only requires $O\left(n^{1 / 2} / r+\log n\right)$ rounds to pass information from a single vertex, to every vertex of the giant. They show on the way that the diameter of the giant is $\Theta\left(n^{1 / 2} / r\right)$ w.h.p. Friedrich, Sauerwald and Stauffer [334] extended this to higher dimensions.

## 数学代写|随机图论代写Random Graph代考|Binomial Random Intersection Graphs

For $G(n, m, p)$ with $m=n^\alpha, \alpha$ constant, Rybarczyk and Stark [694] provided a condition, called strictly $\alpha$-balanced for the Poisson convergence for the number of induced copies of a fixed subgraph, thus complementing the results of Theorem $12.5$ and generalising Theorem 12.7. (Thresholds for small subgraphs in a related model of random intersection digraph are studied by Kurauskas [540]).
Rybarczyk [696] introduced a coupling method to find thresholds for many properties of the binomial random intersection graph. The method is used to establish sharp threshold functions for $k$-connectivity, the existence of a perfect matching and the existence of a Hamilton cycle.
Stark [725] determined the distribution of the degree of a typical vertex of $G(n, m, p)$, $m=n^\alpha$ and showed that it changes sharply between $\alpha<1, \alpha=1$ and $\alpha>1$.
Behrisch [70] studied the evolution of the order of the largest component in $G(n, m, p)$, $m=n^\alpha$ when $\alpha \neq 1$. He showed that when $\alpha>1$ the random graph $G(n, m, p)$ behaves like $\mathbb{G}_{n, p}$ in that a giant component of size order $n$ appears w.h.p. when the expected vertex degree exceeds one. This is not the case when $\alpha<1$. There is a jump in the order of size of the largest component, but not to one of linear size. Further study of the component structure of $G(n, m, p)$ for $\alpha=1$ is due to Lageras and Lindholm in [542].
Behrisch, Taraz and Ueckerdt [71] study the evolution of the chromatic number of a random intersection graph and showed that, in a certain range of parameters, these random graphs can be colored optimally with high probability using various greedy algorithms.

## 数学代写|随机图论代写Random Graph代考|Uniform Random Intersection Graphs

Uniform random intersection graphs differ from the binomial random intersection graph in the way a subset of the set $M$ is defined for each vertex of $V$. Now for every $k=1,2, \ldots, n$, each $S_k$ has fixed size $r$ and is randomly chosen from the set $M$. We use the notation $G(n, m, r)$ for an $r$-uniform random intersection graph. This version of a random intersection graph was introduced by Eschenauer and Gligor [296] and, independently, by Godehardt and Jaworski [389].
Bloznelis, Jaworski and Rybarczyk [106] determined the emergence of the giant component in $G(n, m, r)$ when $n(\log n)^2=o(m)$. A precise study of the phase transition of $G(n, m, r)$ is due to Rybarczyk [697]. She proved that if $c>0$ is a constant, $r=r(n) \geq 2$ and $r(r-1) n / m \approx c$, then if $c<1$ then w.h.p. the largest component of $G(n, m, r)$ is of size $O(\log n)$, while if $c>1$ w.h.p. there is a single giant component containing a constant fraction of all vertices, while the second largest component is of size $O(\log n)$.
The connectivity of $G(n, m, r)$ was studied by various authors, among them by Eschenauer and Gligor [296] followed by DiPietro, Mancini, Mei, Panconesi and Radhakrishnan [259],
Blackbourn and Gerke [95] and Yagan and Makowski [766]. Finally, Rybarczyk [697] determined the sharp threshold for this property. She proved that if $c>0$ is a constant, $\omega(n) \rightarrow \infty$ as $n \rightarrow \infty$ and $r^2 n / m=\log n+\omega(n)$, then similarly as in $\mathbb{G}_{n, p}$, the uniform random intersection graph $G(n, m, r)$ is disconnected w.h.p. if $\omega(n) \rightarrow \infty$, is connected w.h.p. if $\omega(n) \rightarrow \infty$, while the probability that $G(n, m, r)$ is connected tends to $e^{-e^{-c}}$ if $\omega(n) \rightarrow c$. The Hamiltonicity of $G(n, m, r)$ was studied in [109] and by Nicoletseas, Raptopoulos and Spirakis [636].
If in the uniform model we require $\left|S_i \cap S_j\right|>s$ to connect vertices $i$ and $j$ by an edge, then we denote this random intersection graph by $G_s(n, m, r)$. Bloznelis, Jaworski and Rybarczyk [106] studied phase transition in $G_s(n, m, r)$. Bloznelis and Łuczak [108] proved that w.h.p. for even $n$ the threshold for the property that $G_s(n, m, r)$ contains a perfect matching is the same as that for $G_s(n, m, r)$ being connected. Bloznelis and Rybarczyk [110] show that w.h.p. the edge density threshold for the property that each vertex of $G_s(n, m, r)$ has degree at least $k$ is the same as that for $G_s(n, m, r)$ being $k$-connected (for related results see [771]).

Rybarczyk [696] 引入了一种耦合方法来寻找二项式随机交集图的许多属性的阈值。该方法用于建立尖锐 的阈值函数 $k$-连通性，完美匹配的存在性和哈密顿循环的存在。
Stark [725] 确定了典型顶点的度数分布 $G(n, m, p), m=n^\alpha$ 并表明它在之间急剧变化 $\alpha<1, \alpha=1$ 和 $\alpha>1$
Behrisch [70] 研究了最大分量阶数的演变 $G(n, m, p), m=n^\alpha$ 什么时候 $\alpha \neq 1$. 他表明，当 $\alpha>1$ 随机 图 $G(n, m, p)$ 表现得像 $G_{n, p}$ 那是一个巨大的尺寸订单组成部分 $n$ 当预期的顶点度数超过 1 时出现 whp。 情况并非如此 $\alpha<1$. 最大组件的大小顺序有一个跳跃，但不是线性大小之一。进一步研究的组件结构 $G(n, m, p)$ 为了 $\alpha=1$ 归功于 [542] 中的 Lageras 和 Lindholm。
Behrisch、Taraz 和 Ueckerdt [71] 研究了随机相交图的色数的演变，并表明，在一定的参数范围内，可 以使用各种贪心算法以高概率对这些随机图进行最佳着色。

Mancini、Mei、Panconesi 和 Radhakrishnan [259]、
Blackbourn 和 Gerke [95] 以及 Yagan 和 Makowski [766]。最后，Rybarczyk [697] 确定了该属性的尖锐 阈值。她证明了如果 $c>0$ 是常数， $\omega(n) \rightarrow \infty$ 作为 $n \rightarrow \infty$ 和 $r^2 n / m=\log n+\omega(n)$, 然后类似于 $\mathbb{G}_{n, p}$, 均匀随机交集图 $G(n, m, r)$ 断开 whp 如果 $\omega(n) \rightarrow \infty$ ， 连接 $w h p$ 如果 $\omega(n) \rightarrow \infty$ ，而概率 $G(n, m, r)$ 连接趋向于 $e^{-e^{-c}}$ 如果 $\omega(n) \rightarrow c$. 的哈密顿性 $G(n, m, r)$ 在 [109] 以及 Nicoletseas、 Raptopoulos 和 Spirakis [636] 中进行了研究。

## 数学代写|随机图论代写Random Graph代考|RANDOM GEOMETRIC GRAPHS

(c) If $B$ is within distance $100 r$ of two boundary edges of $D$ then $B$ contains no bad cells.

Proof. (a) There are less than $\ell_0^2<n$ such blocks. Furthermore, the probability that a fixed block contains $k_0$ or more bad cells is at most
$$\begin{array}{r} \left(\begin{array}{c} K^2 \ k_0 \end{array}\right)\left(\sum_{i=0}^{i_0}\left(\begin{array}{c} n \ i \end{array}\right)\left(\eta^2 r^2\right)^i\left(1-\eta^2 r^2\right)^{n-i}\right)^{k_0} \ \leq\left(\frac{K^2 e}{k_0}\right)^{k_0}\left(2\left(\frac{n e}{i_0}\right)^{i_0}\left(\eta^2 r^2\right)^{i_0} e^{-\eta^2 r^2\left(n-i_0\right)}\right)^{k_0} \end{array}$$
Here we have used Corollary $23.4$ to obtain the LHS of (12.12).
Now
\begin{aligned} &\left(\frac{n e}{i_0}\right)^{i_0}\left(\eta^2 r^2\right)^{i_0} e^{-\eta^2 r^2\left(n-i_0\right)} \ & \leq n^{O\left(\eta^3 \log (1 / \eta)-\eta^2(1+\varepsilon-o(1)) / \pi\right.} \leq n^{-\eta^2(1+\varepsilon / 2) / \pi}, \end{aligned}
for $\eta$ sufficiently small. So we can bound the RHS of (12.12) by
$$\left(\frac{2 K^2 e n^{-\eta^2(1+\varepsilon / 2) / \pi}}{(1-\varepsilon / 10) \pi / \eta^2}\right)^{(1-\varepsilon / 10) \pi / \eta^2} \leq n^{-1-\varepsilon / 3} .$$
Part (a) follows after inflating the RHS of (12.14) by $n$ to account for the number of choices of block.
(b) Replacing $k_0$ by $k_0 / 2$ replaces the LHS of (12.14) by
$$\left(\frac{4 K^2 e n^{-\eta^2(1+\varepsilon / 2) / \pi}}{(1-\varepsilon / 10) \pi / 2 \eta^2}\right)^{(1-\varepsilon / 10) \pi / 2 \eta^2} \leq n^{-1 / 2-\varepsilon / 6}$$
Observe now that the number of choices of block is $O\left(\ell_0\right)=o\left(n^{1 / 2}\right)$ and then Part (b) follows after inflating the RHS of (12.15) by $o\left(n^{1 / 2}\right)$ to account for the number of choices of block.
(c) Equation (12.13) bounds the probability that a single cell is bad. The number of cells in question in this case is $O(1)$ and (c) follows.
We now do a simple geometric computation in order to place a lower bound on the number of cells within a ball $B(X, r)$.

## 数学代写|随机图论代写Random Graph代考|Chromatic number

We look at the chromatic number of $G_{\mathscr{X}, r}$ in a limited range. Suppose that $n \pi r^2=$ $\frac{\log n}{\omega_r}$ where $\omega_r \rightarrow \infty, \omega_r=O(\log n)$. We are below the threshold for connectivity here. We will show that w.h.p.
$$\chi(G \mathscr{X}, r) \approx \Delta(G \mathscr{X}, r) \approx c l(G \mathscr{X}, r)$$
where will use $c l$ to denote the size of the largest clique. This is a special case of a result of McDiarmid [587].
We first bound the maximum degree.
Lemma 12.13.
$$\Delta\left(G_{\mathscr{X}, r}\right) \approx \frac{\log n}{\log \omega_r} \text { w.h.p. }$$
Proof. Let $Z_k$ denote the number of vertices of degree $k$ and let $Z_{\geq k}$ denote the number of vertices of degree at least $k$. Let $k_0=\frac{\log n}{\omega_d}$ where $\omega_d \rightarrow \infty$ and $\omega_d=$ $o\left(\omega_r\right)$. Then
$$\mathbb{E}\left(Z_{\geq k_0}\right) \leq n\left(\begin{array}{c} n \ k_0 \end{array}\right)\left(\pi r^2\right)^{k_0} \leq n\left(\frac{n e \omega_d \log n}{n \omega_r \log n}\right)^{\frac{\log n}{\omega_d}}=n\left(\frac{e \omega_d}{\omega_r}\right)^{\frac{\log n}{\Phi_d}} .$$
So,
$$\log \left(\mathbb{E}\left(Z_{\geq k_0}\right)\right) \leq \frac{\log n}{\omega_d}\left(\omega_d+1+\log \omega_d-\log \omega_r\right)$$

$$\left(\frac{n e}{i_0}\right)^{i_0}\left(\eta^2 r^2\right)^{i_0} e^{-\eta^2 r^2\left(n-i_0\right)} \quad \leq n^{O\left(\eta^3 \log (1 / \eta)-\eta^2(1+\varepsilon-o(1)) / \pi\right.} \leq n^{-\eta^2(1+\varepsilon / 2) / \pi},$$

$$\left(\frac{2 K^2 e n^{-\eta^2(1+\varepsilon / 2) / \pi}}{(1-\varepsilon / 10) \pi / \eta^2}\right)^{(1-\varepsilon / 10) \pi / \eta^2} \leq n^{-1-\varepsilon / 3}$$
(a) 部分是在将 (12.14) 的 RHS 膨胀后的 $n$ 考虑块的选择数量。
(b) 更换 $k_0$ 经过 $k_0 / 2$ 将 (12.14) 的 LHS 替换为
$$\left(\frac{4 K^2 e n^{-\eta^2(1+\varepsilon / 2) / \pi}}{(1-\varepsilon / 10) \pi / 2 \eta^2}\right)^{(1-\varepsilon / 10) \pi / 2 \eta^2} \leq n^{-1 / 2-\varepsilon / 6}$$

(c) 等式 (12.13) 界定了单个电池坏的概率。在这种情况下，有问题的细胞数量是 $O(1)(\mathrm{c})$ 如下。 我们现在做一个简单的几何计算，以便为球内的细胞数量设置一个下限 $B(X, r)$.
