manifolds sheaves and cohomology springer studium the sheaf of differential forms, for example, one can derive de Rham cohomology, an essential tool in differential topology. Cohomology of Sheaves on Manifolds The cohomological analysis of sheaves on manifolds leads to profound results, such as: De Rham's theorem: Equates de Rh D Darrin Hirthe May 13, 2026
