Our regular seminar program covers a broad range of topics from applied mathematics, pure mathematics and statistics. All staff and students are welcome.
This page has a complete list of past seminars and a list restricted by year can be accessed via the left-hand menu.

*Jianya Liu - Shandong University*

The behavior of the Mobius function is central in the theory of prime numbers. A surprising connection with the theory of dynamical systems was discovered in 2010 by P. Sarnak, who formulated the...

*Adam Harper - University of Warwick*

Random multiplicative functions $f(n)$ are a well studied random model for deterministic multiplicative functions like Dirichlet characters or the Mobius function. Arguably the first question ever...

*Jacob Tsimerman - University of Toronto*

(joint w/ Arul Shankar) We discuss a new method to bound 5-torsion in class groups of quadratic fields using the refined BSD conjecture for elliptic curves. The most natural “trivial” bound on the n-...

*Dragos Ghioca - University of British Columbia*

The Dynamical Mordell-Lang Conjecture predicts the structure of the intersection between a subvariety $V$ of a variety $X$ defined over a field $K$ of characteristic $0$ with the orbit of a point in...

*Jasmin Matz - University of Copenhagen*

Suppose $M$ is a closed Riemannian manifold with an orthonormal basis $B$of $L^2(M)$ consisting of Laplace eigenfunctions. A classical result ofShnirelman and others proves that if the geodesic flow...

*Jason Bell - University of Waterloo*

The degree of a dominant rational map $f:\mathbb{P}^n\to \mathbb{P}^n$ is the common degree of its homogeneous components. By considering iterates of $f$, one can form a sequence ${\rm deg}(f^n)$,...

*Gérald Tenenbaum - Université de Lorraine*

Let $\varrho$ be a complex number and let $f$ be a multiplicative arithmetic function whose Dirichlet series takes the form $\zeta(s)^\varrho G(s)$, where $\zeta(s)$ is the Riemann zeta function and...

*Jens Marklof - University of Bristol*

Take a point on the unit circle and rotate it N times by a fixed angle. The N points thus generated partition the circle into N intervals. A beautiful fact, first conjectured by Hugo Steinhaus in the...

*Gal Binyamini - Weizmann Institute of Science*

I will discuss "point counting" in two broad senses: counting the intersections between a trascendental variety and an algebraic one; and counting the number of algebraic points, as a function of...

*Jörg Brüdern - University of Göttingen*

We study arithmetic functions that are bounded in mean square, and simultaneously have a mean value over any arithmetic progression. A Besicovitch type norm makes the set of these functions a Banach...
