Characterization theorems for $Q$-independent random variables with values in a locally compact Abelian group

Abstract

Let XX be a locally compact Abelian group, YY be its character group. Following A. Kagan and G. Sz\'ekely we introduce a notion of QQ-independence for random variables with values in XX. We prove group analogues of the Cram\'er, Kac-Bernstein, Skitovich-Darmois and Heyde theorems for QQ-independent random variables with values in XX. The proofs of these theorems are reduced to solving some functional equations on the group YY.
