Riemann-Hilbert correspondence for irregular holonomic D-modules
星期一, 22 九月, 2014 - 14:00
Résumé : 

The classical Riemann-Hilbert correspondence establishes an equivalence between the triangulated category of regular holonomic D-modules and that of constructible sheaves.
In a joint work with Masaki Kashiwara, we prove a Riemann-Hilbert correspondence for holonomic D-modules which are not necessarily regular. The construction of our target category is based on the theory of ind-sheaves by Kashiwara-Schapira and influenced by Tamarkin's work. Among the main ingredients of our proof is the description of the structure of flat meromorphic connections due to Mochizuki and Kedlaya.
In this talk I will present an overview of the classical correspondence and the main ideas underlying our construction, sweeping under the carpet the more technical points.
