Adjoint test modules along Cohen--Macaulay morphisms
Abstract
We provide a transformation rule for adjoint test modules along Cohen--Macaulay maps between Cohen--Macaulay varieties that have F-rational geometric fibers. This is, in part, an effective version of Enescu's theorem on the ascent of F-rationality under local maps with F-rational geometric fibers.
