Cartier duality is a concept in the field of algebraic geometry and representation theory, particularly related to schemes and étale cohomology. It is named after the mathematician Pierre Cartier. At its core, Cartier duality establishes a relationship between a finite commutative group scheme over a field and its dual group scheme.
