Bigness of the tangent bundle of del Pezzo surfaces and $D$-simplicity

30 Jun 2020 Mallory Devlin

We consider the question of simplicity of a ring $R$ under the action of its ring of differential operators $D_R$. We give examples to show that even when $R$ is Gorenstein and has rational singularities $R$ need not be a simple $D_R$-module; for example, this is the case when $R$ is the homogeneous coordinate ring of a smooth cubic surface...
