I will report on joint work with Takuma Hayashi (Osaka   University) on a general theory of D-modules over arbitrary base   schemes. As a a motivation and an application, I will explain how to   apply our results to the construction of Harish-Chandra modules over   Z[1/2] with nice properties. This then implies the existence of global   1/2-integral structures on global spaces of automorphic cusp forms.

Welcome!
