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.
