*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...
