In algebraic geometry, Leray's theorem 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 == References == * Bonavero, Laurent.
