Commutativity of integral quasi-arithmetic means on measure spaces

Dorota Głazowska, Paolo Leonetti, Janusz Matkowski +1

Let $(X,\mathcal{L},\lambda )$ and $(Y,\mathcal{M},\mu )$ be finite measure spaces for which there exist $A\in \mathcal{L}$ and $B\in \mathcal{M}$ with $0<\lambda (A)<\lambda (X)$ and $0 < μ(B)…
