Abstract

Given two means M and N, the mean P is called $(M,N)$ -invariant if $P(M,$ $N)=P.$ At the same time the mean N is called complementary to M with respect to P. We use the method of series expansion of means to determine the complementary with respect to a weighted Gini mean. The invariance in the family of weighted Gini means is also studied. The computer algebra Maple was used for solving some complicated systems of equations.
