{{TEX|done}}{{MSC|30H20}}

A family of closed linear operators $\{ a^*(f) : f \in H \}$, where $H$ is some [[Hilbert space]], acting in the [[Fock space]] constructed over $H$. They are the adjoints of the [[annihilation operators]] $\{ a(f) : f \in H \}$.

Cf. [[Annihilation operators]] for a precise description of the operators $a^*(f)$ and for suitable references.
