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...
