### Abstract

Given two continuous functions f, g : I -ℝ R such that g is positive and f/g is strictly monotone, and a probability measure μ on the Borel subsets of [0,1], the two variable mean M_{f,g,μ} : I^{2} → I is defined by M_{f,g,μ}(x,y):=(f/g) ^{-1}(∫_{0}^{1}f(tx+(1-t)y)dμ(t) /∫_{0}^{1}g(tx+(1-t)y)dμ(t))(x,y ∈I). The aim of this paper is to study Minkowski-type inequalities for these means, i.e., to find conditions for the generating functions f_{0},g_{0} : I_{0} → R, f_{1}, g_{1} : I_{1} → R,., f_{n}, g_{n} : In→ R, and for the measure μ such that M_{f0,g0:μ}(x_{1}+.+x_{n},y_{1}+.+y _{n}) ≤ [≥] Mf_{1},g1;μ(x_{1},y _{1})+.+Mf_{n},g0,μ(x_{n},y_{n}) holds for all x_{1},y_{1} ∈ I_{1}, ., x_{n},y _{n} ∈ I_{n} with x_{1} + . + x_{n},y _{1}+.+y_{n} ∈ I_{0}. The particular case when the generating functions are power functions, i.e., when the means are generalized Gini means is also investigated.
