 Gelfand–Fuks cohomology

Gelfand–Fuks cohomology is a concept in the field of mathematics that arises from the study of infinite-dimensional Lie algebras and their representations. It provides a powerful tool for analyzing and understanding the structure of these algebras, particularly in the context of the theory of differential operators and the geometry of manifolds. The cohomology theory was developed by Israel Gelfand and Sergei Fuks in the 1960s.
