Creation operators

2020 Mathematics Subject Classification: Primary: 30H20 [MSN][ZBL]

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 $\\{ a(f) : f \in H \\}$.

#### Comments[edit]

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