Bargmann-Fock space

(Definition)

The Bargmann-Fock space (or simply Fock space) is the Hilbert space of entire functions, $\mathcal{F}^2(\mathbb{C})$ s.t.

$\displaystyle \int_\mathbb{C}\vert F(z)\vert^2 e^{- \pi \vert z\vert^2}dx dy<\infty$

with associated inner product

$\displaystyle \int_\mathbb{C}F(z)\overline{G(z)}e^{- \pi \vert z\vert^2}dx dy$
