Abstract
We show that for fixed k the k-th homotopy group of a finite simply connected simplicial complex is polynomial-time computable. Simultaneously, we prove that the problem of extending a continuous map to simply connected space is undecidable in general.
Abstract (in Czech)
Pro pevné k lze provést výpočet k-té homotopické grupy v polynomiálním čase. Z druhé strany, problém zda lze dané zobrazením do jednoduše souvislé simpliciální množiny rozšířit je nerozhodnutelný.
