= Berezin transform
{wiki=Berezin_transform}
The Berezin transform, also known as the Berezin integral or Berezin symbol, is a mathematical operation used in the context of quantization and the study of operators in quantum mechanics, particularly within the framework of the theory of pseudodifferential operators and the calculus of symbol. In essence, the Berezin transform allows one to associate an operator defined on a space of functions (often in a Hilbert space) with a corresponding function (or symbol) defined on the phase space.
