Abstract
Let
be the collection of parallelepipeds in Rκ with edges parallel with the coordinate axes and let
be the collection of closed sets in Rκ. Let π(G, H)=inf {ε∣G{A}⩽H{Aε}+ε, H{A}⩽G{Aε}+ε for any
; L(G, H)= inf {ε∣G{A}⩽H{Aε}+ε, H{A}⩽G{Aε}+ε for any
, where G, H are distributions in\(R^\kappa ,A^\varepsilon = \left\{ {x \in R^\kappa \left| {\mathop {\inf }\limits_{y \in A} } \right.\left\| {x - y} \right\|< \varepsilon } \right\}\). In the paper one gives the proofs of results announced earlier by the author (Dokl. Akad. Nauk SSSR,253, No. 2, 277–279 (1980)). One considers the problem of the approximation of the distributions of sums of independent random vectors with the aid of infinitely divisible distributions. One obtains estimates for the distances π(·, ·), L(·, ·) and
. It is proved that
