*Ming Zhong - Johns Hopkins University*

Collective behaviors (clustering, flocking, milling, etc.) are among the most interesting and challenging phenomena to understanding from the mathematical point of view. We offer a non-parametric...

*Shayo Olukoya - University of St Andrews, Scotland*

Abstract: The class of full and sufficiently transitive (i.e. flexible) groups of homeomorphisms of Cantor space contains many groups of interest including generalisations of the Higman-Thompson...

*Patrick Morris - Freie Universität Berlin, Berlin Mathematical School*

An $(n,d,\lambda)$-graph is an $n$ vertex, $d$-regular graph with second eigenvalue in absolute value $\lambda$. When $\lambda$ is small compared to $d$, such graphs have \emph{pseudorandom}...

*Man-Wai Cheung (Mandy) - University of Harvard*

Cluster varieties are log Calabi-Yau varieties which are unions of algebraic tori glued by birational "mutation" maps. They can be seen as a generalization of the toric varieties. In toric geometry...

*Anna Romanov - University of Sydney*

This is a talk about my favourite theorem. The Beilinson—Bernstein localisation theorem provides a concrete link between two seemingly disparate mathematical worlds: the world of Lie theory (the...

*Kevin Shen - UNSW Sydney*

George Boole introduced Boolean algebra in 1847 and since then it has played a central role in various areas such as logic circuit design, complexity theory and propositional logic. The conventional...

*Mike Steel - University of Canterbury*

In the 161 years since Darwin’s Origin of Species, biologists have developed sophisticated ways to uncover and study the hidden shared ancestry of life from genomic data. While Darwin was able to...

*Dinakar Muthiah - University of Glasgow*

A common goal in algebraic geometry is to understand a geometric object as a moduli space. One fundamental difficulty is determining whether the proposed moduli space is reduced, i.e. that the...

*Behrouz Taji - University of Sydney*

In the 1920s, building on Fermat's Last Theorem, Mordell conjectured that the set of rational points of any smooth projective curve of genus at least two, over any number field, is finite. In the...

*Ryan Seelig - UNSW Sydney*

To avoid paradoxes, the geometry of physics at the very smallest scales must be non-commutative. The symmetries of such a geometry constitute a structure called a Quantum Group. In this talk we build...
