Joint USYD-UNSW Seminar on SPDEs: Marco Carfagnini -- Spectral gaps via small deviations

https://unsw.zoom.us/j/87938114945?from=addon Meeting ID: 87938114945 Password (if
required): 859718 

ABSTRACT.  In this talk we will discuss spectral gaps of second order differential
operators and their connection to limit laws such as small deviations and Chung laws
of the iterated logarithm.  The main focus is on hypoelliptic diffusions such as the
Kolmogorov diffusion and horizontal Brownian motions on Carnot groups.  If time permits,
we will discuss spectral properties and existence of spectral gaps on general Dirichlet
metric measure spaces.  This talk is based on joint works with Maria (Masha) Gordina and
Alexander (Sasha) Teplyaev
