Abstract

Holonomic D-modules play an important role in commutative algebra. Their definition and proofs of their elementary properties are quite simple over polynomial rings but considerably more complicated over formal power series. In this talk I will present the very recent work of my student Peyman Gharemani which considerably simplifies the proofs of some important aspects of the theory in the formal power series case.
