FORMALLY REGULAR RINGS AND DESCENT OF REGULARITY

open access: yesJournal of the Institute of Mathematics of Jussieu
AbstractValuation rings and perfectoid rings are examples of (usually non-Noetherian) rings that behave in some sense like regular rings. We give and study an extension of the concept of regular local rings to non-Noetherian rings so that it includes valuation and perfectoid rings and it is related to Grothendieck’s definition of formal smoothness as ...

A generalized time fractional Schrödinger equation with signed potential

open access: yesCommunications in Analysis and Mechanics
In this work, by stochastic analyses, we study stochastic representation, well-posedness, and regularity of generalized time fractional Schrödinger equation $ \begin{equation*} \left\{\begin{aligned} \partial_t^wu(t,x)& = \mathcal{L} u(t,x)-\kappa(
