Operator

This is an old revision of this page, as edited by MexMax (Talk | contribs) at 21:46, 15 November 2007. It may differ significantly from current revision.

An operator is a map from function space to function space. If the range of an operator is on the real line or in the complex plane, the operator is usually called a functional instead.

An operator is also a person who makes phone connections, though this practice is becoming less common as the process becomes more automated.
