Definition(s)
-
In mathematics, specifically in functional analysis, a C*-algebra (pronounced "C-star") is a Banach algebra together with an involution satisfying the properties of the adjoint. A particular case is that of a complex algebra A of continuous linear operators on a complex Hilbert space with two additional properties :
- A is a topologically closed set in the norm topology of operators.
- A is closed under the operation of taking adjoints of operators.
