On the Geometric Ramsey Number of Outerplanar Graphs

Josef Cibulka, Pu Gao, Marek Krčál +2

We prove polynomial upper bounds of geometric Ramsey numbers of pathwidth-2 outerplanar triangulations in both convex and general cases. We also prove that the geometric Ramsey num…

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…

Extendability of continuous maps is undecidable

Martin Cadek, Marek Krcal, Jiri Matousek +2

We consider two basic problems of algebraic topology, the extension problem and the computation of higher homotopy groups, from the point of view of computability and computational…
