Idea

A commutative $C^\ast$-algebra is a C-star algebra whose underlying associative algebra is a commutative algebra.

Properties

Commutative $C^\ast$-algebras are those identified by Gelfand duality with algebras of continuous functions on compact Hausdorff topological spaces.

Relation to KK-theory

Example

Every commutative C-algebra is a nuclear C*-algebra.
