In algebraic topology, homotopical connectivity is a property describing a topological space based on the dimension of its holes. In general, low homotopical connectivity indicates that the space has at least one low-dimensional hole. The concept of n-connectedness generalizes the concepts of … Meer weergeven All definitions below consider a topological space X. A hole in X is, informally, a thing that prevents some suitably-placed sphere from continuously shrinking to a point. Equivalently, … Meer weergeven Many topological proofs require lower bounds on the homotopical connectivity. There are several "recipes" for proving such lower bounds.
