Nonlocal operators of Kolmogorov type and their extensions

Mercoledì 20 febbraio 2019, ore 12.00, aula M1.6, primo piano, edificio Matematica, Dipartimento FIM, Modena.

Relatore: Nicola Garofalo (Università di Padova).

Abstract: In this talk I present a new general procedure for defining the fractional powers of a fairly large class of second order partial differential operators first introduced by Hormander in his seminal 1967 work on the hypoellipticity. In the process I present a new version of the so-called extension problem for such operators, and provide an explicit construction for its solution. If time allows I will discuss some interesting applications of the relevant results. This is joint work with Giulio Tralli.

Host: Sergio Polidoro.
