Abstract:
Let a locally compact abelian group X=Rn×G, where G contains a compact open subgroup K, F is a finite measure on X and
e(F)=exp{−F(X)}∞∑k=0F∗k/k!
is a generalized Poisson distribution.
Theorem 1. {\it If F(X)<1/2ln2 and the measures F∗m and F∗k are mutually singular for any different integers m and k then e(F) has no indecomposable divisors.}
Theorem 2.An absolutely continuous measure F on X such that e(F) has no indecomposable divisors exists if and only if one of the following conditions is satisfied:
(α) n=0 and factor-group G/K contains an element of infinite order,
(β) n>0.
