Fixed point theorems for topological contractions and the Hutchinson operator

Michał Morayne, Robert Rałowski

For a topological space $X$ a topological contraction on $X$ is a closed mapping $f : X \to X$ such that for every open cover of $X$ there is a positive integer $n$ such that the imag…

A note on Hutchinson operator in $T_{1}$ compact topological spaces

Michał Morayne, Robert Rałowski

In $T_{1}$ compact topological spaces the Hutchinson operator of a contractive IFS (iterated function system; a finite family of closed mappings from the space into itself) may not b…
