Query: Asymptotics of Discrete Chebyshev Polynomials   The discrete Chebyshev polynomials $t_n(x,N)$ are orthogonal with respect to
a distribution, which is a step function with jumps one unit at the points
$x=0,1,\cdots, N-1$, $N$ being a fixed positive integer. By using a double
integral representation, we have recently obtained asymptotic expansions for
$t_{n}(aN,N+1)$ in the double scaling limit, namely, $N\rightarrow\infty$ and
$n/N\rightarrow b$, where $b\in (0,1)$ and $a\in(-\infty,\infty)$; see [Studies
in Appl. Math. \textbf{128} (2012), 337-384]. In the present paper, we continue
to investigate the behaviour of these polynomials when the parameter $b$
approaches the endpoints of the interval $(0,1)$. While the case $b\rightarrow
1$ is relatively simple (since it is very much like the case when $b$ is
fixed), the case $b\rightarrow 0$ is quite complicated. The discussion of the
latter case is divided into several subcases, depending on the quantities $n$,
$x$ and $xN/n^2$, and different special functions have been used as
approximants, including Airy, Bessel and Kummer functions.
