An element of the space , the dual of the space of analytic functions defined on an open subset of , i.e. a functional on . Thus, a distribution with compact support is an analytic functional. There exists a compact set , said to be the support of the analytic functional , on which is concentrated: For any open set the functional can be extended to so that for all the following inequality is valid:

where is a constant depending on . There exists a measure with support in such that

An analytic functional is defined in a similar manner on a space of real-valued functions.
