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.

Catherine Greenhill - University of New South Wales
The small subgraph conditioning method was introduced by Robinson and Wormald (1992, 1994) to prove that a random $r$-regular graph contains a Hamilton cycle with probability which tends to 1 as the...

Peter Tingley - Loyola University Chicago
We present an elementary construction of Lusztig's canonical basis. The method, which is essentially Lusztig's original approach, uses the braid group to reduce to rank two calculations. Some of the...

Lia Vas - University of the Sciences, Philadelphia, USA
I have been working in algebra and ring theory, in particular with rings of operators, involutive rings, Baer *-rings and Leavitt path algebras. These rings were introduced in order to simplify the...

Emily Peters - Loyola University Chicago
Maybe you've heard of diagram algebras, planar algebras, "spiders" or something similar. And you're wondering, is this really math? Are the pictures an analogy or are they actual mathematical objects...

Marija Cvetković - University of Niš, Serbia
Perov's theorem is one of many different extensions of the famous Banach fixed point theorem, one which is notable for its wide spectra of applications. It claims existence and uniqueness of a fixed...

Kwok-kun Kwong - National Cheng Kung University
The well-known Alexandrov theorem states that the only closed embedded surfaces with constant mean curvature in Euclidean space are the round spheres. There are many generalizations, commonly known...

Quanshui Wu - Fudan University
I will talk about Poisson cohomology and Batlin-Vilkovisky algebra structure on it, in contrast Hochschild cohomology. I will concentrate on the Frobenius case after the introduction part.

Dietmar Bisch - Vanderbilt University
An inclusion of certain algebras of operators on Hilbert sapce is called a subfactor. It is a mathematical object with an extremely interesting representation theory that is similar in many ways to...

Detlef Müller - University of Kiel
In this  survey talk, I shall try to give an idea about what is known on spectral multiplier estimates of Mihlin-Hörmander type for sub-Laplacians and what are the challenges in their still wide open...

Maike Massierer - University of New South Wales
Let $C/Q$ be a curve of genus 3, given as a double cover of a plane conic.  Such a curve is hyperelliptic over the algebraic closure of $Q$, but may not have a hyperelliptic model of the usual form...
