Department of Mathematics Colloquia

The talks are  relaxed and non-technical and they are accessible to all the postgraduate students. They are followed by a drinks reception.


Tuesday, 9 October 2018 at 3.30 pm

Location: Franklin-Wilkins Building 3.52, Waterloo Campus

Speaker:  Professor Eugenia Malinnikova (Norwegian University of Science                         andTechnology)

Title: An improvement of the Liouville theorem for discrete harmonic functions

Abstract: We discuss the discrete version of the Laplace operator on the standard lattice Z^2 and Z^d. On Z^2, we prove that if a harmonic function is bounded on a large portion of the lattice then it is constant. This is no longer true on Z^d, d>2. The talk is based on a joint work with L. Buhovsky, A. Logunov and M. Sodin.
