About: Leray's theorem

An Entity of Type: Abstraction100002137, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

In algebraic topology and algebraic geometry, Leray's theorem (so named after Jean Leray) relates abstract sheaf cohomology with Čech cohomology. Let be a sheaf on a topological space and an open cover of If is acyclic on every finite intersection of elements of , then where is the -th Čech cohomology group of with respect to the open cover
