On open covers of aspherical spaces satisfying ${\pi }_1$-constraints and bounded Adamson cohomology

Arturo Espinosa Baro, Stephan Mescher

Given a topological space $X$ and a family of subgroups $\mathcal{F}$ of ${\pi }_1(X)$, the $\mathcal{F}$-category of $X$ is given as one less than the cardinality of the smallest cover…
