*Cain Edie-Michell - Vanderbilt University, USA*

Quantum subgroups are module categories, which encode the ``higher representation theory'' of the Lie algebras. They appear naturally in mathematical physics, where they correspond to extensions of...

*Rosalind Cameron - (University of Canterbury)*

The vertex-pursuit game of cops and robbers, introduced by Nowakowski and Winkler (1983), is played on a graph where a team of cops aim to occupy the same vertex as the robber. The cop number of a...

*Stephan Tornier - University of Newcastle*

Following a motivation of groups acting on trees by situating them within the broader theory of all (locally compact) groups, I demonstrate that the ’global’ structure of such a group is innately...

*Visu Markam - Institute for Advanced Study and University of Melbourne*

The study of symmetries in the setting of group actions via "invariant" polynomials is called invariant theory. Computation has played a key role in the evolution of invariant theory from its very...

*Anna Puskás - The University of Queensland, Australia*

The study of objects from number theory such as metaplectic Whittaker functions has led to surprising applications of combinatorial representation theory. Classical Whittaker functions can be...

*Sophie Spirkl - University of Waterloo*

The Erdős-Hajnal conjecture states that for every graph $H$ there exists $c>0$ such that every $n$-vertex graph $G$ either contains $H$ as an induced subgraph, or has a clique or stable set of...

*Davide Ravotti - Monash University*

Abstract: Parabolic flows are smooth flows for which nearby points diverge slowly (namely, at polynomial speed) and include, for example, smooth area-preserving flows on surfaces, horocycle flows and...

*Dr Shane Keating - UNSW SYDNEY*

This hands-on interactive workshop will demonstrate innovative online educational resources for University-level courses in atmosphere, ocean, and climate science. We will work through a suite of web...

*Urs Fuchs - Monash University*

Pseudoholomorphic curves were introduced by Gromov as a fundamental tool for the study of symplectic manifolds. I will review some applications of pseudoholomorphic curves in symplectic geometry,...

*Rudi Mrazović - University of Zagreb*

Hall and Paige conjectured in 1955 that a finite group G has a complete mapping (a permutation F such that xF(x) is also a permutation) if and only if it satisfies a straightforward necessary...
