Abstract

We prove a quantum version of the localization formula of Witten $\href{https://mathscinet.ams.org/mathscinet/relay-station?mr=1185834}{[31]}$, see also $[\href{https://mathscinet.ams.org/mathscinet/relay-station?mr=1792291}{28}$, $\href{https://mathscinet.ams.org/mathscinet/relay-station?mr=1722000}{22}$, $\href{https://mathscinet.ams.org/mathscinet/relay-station?mr=2198772}{35}$], that relates invariants of a GIT quotient with the equivariant invariants of the action.
