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…

The hyperspace of k-dimensional closed convex sets

Adriana Escobedo-Bustamante, Natalia Jonard-Pérez

For every $n \geq 2$ , let $K_{k}^{n}$ denote the hyperspace of all $k$ -dimensional closed convex subsets of the Euclidean space $R^{n}$ endowed with the Atouch-Wets topology. Let $ K_{k,…
