Hecke algebra

In mathematics, a Hecke algebra can be one of several algebras, similar to the algebra of Hecke operators studied by Erich Hecke. The algebra of Hecke operators can be interpreted as an algebra of double cosets, and as a result the term 'Hecke algebra' is also used for several similar algebras related to double cosets. In particular it can mean: In mathematics, a Hecke algebra can be one of several algebras, similar to the algebra of Hecke operators studied by Erich Hecke.
