## Computing high-quality Lagrangian bounds of the stochastic mixed-integer programming problem »

Andrew Eberhard (RMIT University)
4pm 5 April 2018

The solution of stochastic optimisation problem in their deterministic equivalent form is intractable, for moderate sized problems, due to the exponential increase in size of the problem with scenarios and with stage number.

## From ADE to Fermat curves and beyond: modular invariants for the quantum groups »

Terry Gannon (University of Alberta)
3.30pm 3 April 2018

In 1987, Cappelli-Itzykson-Zuber classified the conformal field theories (more precisely their modular invariant partition functions) associated to the sl(2) quantum groups.

## The Kato Square Root Problem for Divergence Form Operators with Potential »

Julian Bailey (MSI)
1.30pm 3 April 2018

The Kato square root problem for divergence form elliptic operators is the equivalence statement $\norm{\sqrt{- \mathrm{div} \br{A \nabla}}u} \simeq \norm{\nabla u}$, where  $A$ is a complex matrix-valued function.

Arik Wilbert (The University of Sydney)
3.30pm 27 March 2018

The Springer correspondence in type A provides a bijection between nilpotent orbits for the general linear group and complex, finite-dimensional, irreducible representations (up to isomorphism) of the symmetric group.

## Quantum G2 at roots of unity: diagrams vs. algebra »

Noah Snyder (Indiana)
3.30pm 20 March 2018

For generic $q$, Kuperberg's $G_2$ spider agrees with the category of representations of the quantum group.  What happens when $q$ is a root of unity?
