The next meeting of the Joint Seminar of Analysis, Geometry and Topology Department will be held on May 18, 2021 at 14:00 via ZOOM. A talk on:

Formal neighbourhoods in the space of arcs

will be delivered by Peter Petrov.

Everybody is invited.

Abstract. After introducing briefly jet and arc spaces I will discuss the notion of formal neighbourhood of a point. Then the theorem of Drinfeld-Grinberg-Kazhdan representing the formal neighbourhood of a non-degenerate arc will be formulated. Finally, I will discuss some possible generalizations.
