Query: On the Vanishing Criterion for the Cohomology Groups of the Automorphism
  Group of a finite Abelian $p$-Group   For a partition $\underline{\lambda} =
(\lambda_{1}^{\rho_1}>\lambda_{2}^{\rho_2}>\lambda_{3}^{\rho_3}>\ldots>\lambda_{k}^{\rho_k})$
and its associated finite abelian $p$-group
$\mathcal{A}_{\underline{\lambda}}=\underset{i=1}{\overset{k}{\oplus}}
(\mathbb{Z}/p^{\lambda_i}\mathbb{Z})^{\rho_i}$, where $p$ is a prime, we
consider two actions of its automorphism group
$\mathcal{G}_{\underline{\lambda}}$ on $\mathcal{A}_{\underline{\lambda}}$. The
first action is the natural action $g\bullet a=\ ^ga$ for all
$g\in\mathcal{G}_{\underline{\lambda}}$ and
$a\in\mathcal{A}_{\underline{\lambda}}$ where the action map is denoted by
$\Lambda_1=Id_{\mathcal{G}_{\underline{\lambda}}}:\mathcal{G}_{\underline{\lambda}}\longrightarrow
\mathcal{G}_{\underline{\lambda}}$ and the second action is the trivial action
$g\bullet a=a$ for all $g\in\mathcal{G}_{\underline{\lambda}}$ and
$a\in\mathcal{A}_{\underline{\lambda}}$ where the action map is denoted by
$\Lambda_2:\mathcal{G}_{\underline{\lambda}}\longrightarrow
\{e\}\subset\mathcal{G}_{\underline{\lambda}}$ the trivial map. For the natural
action $\Lambda_1$, we show that the first and second cohomology groups
$H_{\Lambda_1}^i(\mathcal{G}_{\underline{\lambda}},\mathcal{A}_{\underline{\lambda}}),i=1,2$
vanish for any partition $\underline{\lambda}$ for an odd prime $p$. For the
trivial action $\Lambda_2$ we show that, for an odd prime $p$, the first
cohomology group
$H_{\Lambda_2}^1(\mathcal{G}_{\underline{\lambda}},\mathcal{A}_{\underline{\lambda}})$
and for an odd prime $p\neq 3$, the second cohomology group
$H_{\Lambda_2}^2(\mathcal{G}_{\underline{\lambda}},\mathcal{A}_{\underline{\lambda}})$
vanish if and only if the difference between two successive parts of the
partition $\underline{\lambda}$ is at most one. This is done by using the $mod\
p$ cohomologies
$H^i(\mathcal{G}_{\underline{\lambda}},\mathbb{Z}/p\mathbb{Z}),i=1,2$.
