On Computability and Triviality of Well Groups

Peter Franek, Marek Krcal

The concept of well group in a special but important case captures homological properties of the zero set of a continuous map $f : K \to R^{n}$ on a compact space K that are invariant w…

Algorithmic solvability of the lifting-extension problem

Martin Čadek, Marek Krčál, Lukáš Vokřínek

Let $X$ and $Y$ be finite simplicial sets (e.g. finite simplicial complexes), both equipped with a free simplicial action of a finite group $G$ . Assuming that $Y$ is $d$ -connected…
