We determine the form of all semiflows of pairs of weighted quasi-arithmetic means, those over positive dyadic numbers as well as the continuous ones. Then the iterability of such pairs is characterized: necessary and sufficient conditions for a give

We determine all pairs Aμφ,Aνψ of weighted quasi-arithmetic means being square iterative roots of another pair Asf,Atg, that is we find all continuous strictly monotonic functions f,g,φ,ψ and parameters s,t,μ,ν∈(0,1) such that the equationA

If the difference of two real homographic functions is nonnegative, then it is constant. Motivated by this property, we determine all pairs of subcommuting (supercommuting) real homographic functions. Simple modification of subcommuting functions tra

We prove that if a uniformly bounded (or equidistantly uniformly bounded) Nemytskij operator maps the space of functions of bounded ${\it\varphi}$-variation with weight function in the sense of Riesz into another space of that type (with the same wei

Let $(X, \mathscr{L}, \lambda)$ and $(Y, \mathscr{M}, \mu)$ be finite measure spaces for which there exist $A \in \mathscr{L}$ and $B \in \mathscr{M}$ with $0 < \lambda(A) < \lambda(X)$ and $0 < \mu(B) < \mu(Y)$, and let $I\subseteq \mathbf{R}$ be a

We prove that if the composition operator F generated by a function f: [a, b] × ℝ → ℝ maps the space of bounded (p, k)-variation in the sense of Riesz-Popoviciu, p ≥ 1, k an integer, denoted by RV(p,k)[a, b], into itself and is uniformly bou
