Test elements in equal characteristic semianalytic algebras

Abstract: We establish a series of results showing that the Jacobian ideal is contained in the test ideal. We first prove a new result in characteristic $p$ for complete rings over a field $K$. Then we prove some results showing that Jacobian ideals are contained in test ideals in equal characteristic 0 for affine, analytic, affine-analytic and semianalytic $K$-algebras.
