Decreasing involutions and $Z_{2}$ -means

Natalia Jonard-Pérez, Ananda López-Poo

An $n$ -mean on a topological space $X$ is a continuous symmetric map $p : X^{n} \to X$ satisfying $p (x, \dots, x) = x$ for every $x \in X$ . If $X$ is a $G$ -space, such an $n$ -mean is…

Some notes on induced functions and group actions on hyperspaces

Victor Donjuán, Natalia Jonard-Pérez, Ananda López-Poo

We discuss the problem of when a continuous map between topological spaces induces a continuous function between their respective hyperspaces. We characterize the continuity of the…
