Abstract
We prove a generalization of the Hochster-Roberts-Boutot-Kawamata Theorem conjectured by Aschenbrenner and the author: let be a pure homomorphism of equicharacteristic zero Noetherian local rings. If is regular, then is pseudo-rational, and if is moreover -Gorenstein, then it pseudo-log-terminal.
