Kotlarski characterized the
distribution of three independent real random variables X1,X2,X3 having
nonvanishing characteristic functions by the joint distribution of the 2-dimensional
vector (X1 + X8,X2 + X3). In this paper, we shall give a generalization of
Kotlarski’s result for X1,X2,Xa n-dimensional random variables having analytic
characteristic functions which can meet the value zero.
