• ### Analysis Seminar

Tuesday January 22, 2019 at 14:00, Wachman 617 (note special day and time)

Alessia Elisabetta Kogoj, University of Urbino "Carlo Bo"

Several Liouville-type theorems are presented, related to evolution equations on Lie Groups and to their stationary counterpart. Our results apply in particular to the heat operator on Carnot groups, to linearized Kolmogorov operators and to operators of Fokker-Planck-type like the Mumford operator. An application to the uniqueness for the Cauchy problem is also shown.

These results are based on joint publications with A. Bonfiglioli, E. Lanconelli, Y. Pinchover and S. Polidoro.

• ### Probability Seminar

• ### Geometry and Topology Seminar

Surfaces almost transverse to circular pseudo-Anosov flows

Michael Landry, Yale University

Let $M$ be a closed hyperbolic 3-manifold which fibers over $S^1$, and let $F$ be a fibered face of the unit ball of the Thurston norm on $H^1(M;R)$. By results of Fried, there is a nice flow on $M$ naturally associated to $F$. We study surfaces which are almost transverse to $F$ and give a new characterization of the set of homology directions of $F$ using Agol’s veering triangulation of an auxiliary cusped 3-manifold.
