= K-homology
{wiki=K-homology}
K-homology is a cohomology theory in the field of algebraic topology that provides a way to study topological spaces using tools from K-theory. It is a variant of K-theory where one considers the behavior of vector bundles and their generalizations over spaces. K-homology is mainly applied in the framework of noncommutative geometry and has connections to several areas such as differential geometry, the theory of operator algebras, and index theory.
