Hecke algebra (disambiguation)

In mathematics, a Hecke algebra is classically the algebra of Hecke operators studied by Erich Hecke. It may also refer to one of several algebras generalizing the classical Hecke algebra:
 * Hecke algebra of a pair (G,K) where G is a reductive Lie group and K is a compact subgroup of G.
 * Hecke algebra of a finite group, the algebra spanned by the double cosets HgH of a subgroup H of a finite group G.
 * Iwahori–Hecke algebra of a Coxeter group, corresponding to the case when G is the finite Chevalley group over a finite field and K is its Borel subgroup.
 * Affine Hecke algebra
