{title2=$\mathcal F_\pm(H)$}

For a one-particle <Hilbert space> $H$, the bosonic or fermionic <Fock space> is $\mathcal F_\pm(H)=\bigoplus_{n=0}^{\infty}H^{\otimes_\pm n}$, using symmetric or antisymmetric tensor powers. Its zeroth summand is the one-dimensional vacuum sector. <Creation operators> and <annihilation operators> change particle number. The <bosonic Fock space> and <fermionic Fock space> implement the corresponding exchange statistics.
