Good cover
- abstract: In mathematics, an open cover of a topological space X is a set of open subsets such that X is the union of all of the open sets. In algebraic topology, an open cover is called a good cover if all open sets and all multiple intersections, U_{\alpha_1 \ldots \alpha_n} = U_{\alpha_1 \ldots \alpha_{n-1}} \cap U_{\alpha_n}, are contractible.
