Title: Differential operators and algebra retracts

Abstract: I will define rings of differential operators, and discuss the few explicitly known examples. Using algebra retracts (subrings that are also quotients) I will show how to compute the rings of differential operators on toric face rings. All the terminology will be introduced in the talk, no background on differential operators or toric face rings is necessary. This is joint work with Berkesch, Chan, Klein, Page and Vassilev.
