On the Law of Large Numbers and Convergence Rates for the Random Projections

The aim of this paper is to establish the Marcinkiewicz-Zygmund (MZ) type law of large numbers for the randomly weighted sums with weights chosen randomly, uniformly over the unit sphere in $\mathbb{R}^n$. We also establish a theorem that describes the rate of convergence in the law of large numbers for these weighted sums.

On Equality of Certain Automorphism Groups

Let $G = H\times A$ be a group, where $H$ is a purely non-abelian subgroup of $G$ and $A$ is a non-trivial abelian factor of $G$. Then, for $n \geq 2$, we show that there exists an isomorphism $ϕ: Aut_{Z(G)}^{γ_{n}(G)}(G) \rightarrow Aut_{Z(H)}^{γ_{n}(H)}(H)$ such that $ϕ(Aut_{c}^{n-1}(G))=Aut_{c}^{n-1}(H)$. Also, for a finite non-abelian $p$-group $G$ satisfying a certain natural hypothesis, we give some necessary and sufficient conditions for $Autcent(G) = Aut_c^{n-1}(G)$. Furthermore, for a finite non-abelian $p$-group $G$ we study the equality of $Autcent(G)$ with $Aut_{Z(G)}^{γ_{n}(G)}(G)$.
