Coming Seminars

Our regular seminar program covers a broad range of topics from applied mathematics, pure mathematics and statistics. All welcome, especially students. A complete list of past seminars can be accessed via the left-hand menu.

Bryce Kerr
This talk concerns some recent results joint with Igor Shparlinski and Kam Hung Yau regarding estimates for multiplicative character sums modulo a prime number. We review the Burgess bound for such sums and show how to obtain a logarithmic...

Professor Timoteo Carletti
  Spatially non-homogenous states (patterns) can spontaneously emerge in a multitude of Natural of human made systems. In many cases of interest, the interplay between nonlinearities and diffusion seeds a symmetry breaking instability (...

Vinoth Nandakumar
The irreducible representations of the general linear Lie algebra in positive characteristic are difficult to understand. Lusztig's conjectures, now a theorem of Bezrukavnikov and Mirkovic, describe the dimensions using techniques from geometric...

Caroline Turnage-Butterbaugh
The Riemann zeta-function is a ubiquitous, yet mysterious, function in number theory. The importance of its so-called nontrivial zeros stems from the relationship between the location of these zeros and the distribution of the primes. In fact, the...

Professor Sergei Fedotov
I present a new single integro-differential wave equation for a classical one-dimensional Levy walk. It generalizes the well-known telegraph or Cattaneo equation for the persistent random walk with the exponential switching time distribution. I...

Professor Katsuto Tanaka
Dealing with nonstationary panel models with the error term following the AR(1) process, we examine cross-sectional effects of regressors on the asymptotic properties of panel unit root tests. For this purpose we consider various types of common and...

Gunther Uhlmann
Inverse problems arise in all fields of science and technology where causes for a desired or observed effect are to be determined. By solving an inverse problem is in fact how we obtain a large part of our information about the world. An example is...
