Serre duality is a fundamental theoretical result in algebraic geometry and algebraic topology that relates cohomology groups of a projective variety, or a more general topological space, in a way that connects singular cohomology with dual spaces. Named after Jean-Pierre Serre, the duality provides a bridge between the geometry of a space and its cohomological properties.
