Arieh Iserles - University of Cambridge
Equations of quantum mechanics in the semiclassical regime present an enduring challenge for numerical analysts, because their solution is highly oscillatory and evolves on two scales. Standard...

Ivan Graham - University of Bath
When solving the linear space-time wave equation in the band limited case,  it  is attractive to reduce the problem to one in space only  by applying the Fourier transform in time.  The result  is...

Chris Bourne - ANU
Topological insulators are characterised by quantum mechanical Hamiltonians that obey particular (possibly anti-linear) symmetries, and give rise to edge states `protected’ by these symmetries. We...

Dr. Vera Roshchina - RMIT University
The facial structure of general closed convex cones can be very complex (often surprisingly so). I will talk about two notions that capture the regularity properties of facial arrangements: facial...

Extremal Set Theory is a branch of Extremal Combinatorics where one characterises the maximum size of a family of sets with certain restriction on them. The Erdős-Ko-Rado Theorem is a classical...

Peter Ayre - UNSW
A hypergraph is $k$-uniform if every hyperedge contains $k$ vertices. A colouring of a hypergraph is an assignment of colours to the vertices such that no hyperedge is monochromatic. We consider the...

Professor Wolfgang Hackbusch - Max Planck Institute for Mathematics in the Sciences, Germany
The numerical tensor calculus is an efficient tool for treating high-dimensional objects. The tensor formats involve certain representation ranks. The crucial question is the relation between these ...

Dr Katharina Hees - Universität Heidelberg
Continuous Time Random Maxima (CTRM) are a generalization of the classical Extreme value theory: Instead of observing random events at regular intervals in time or with exponential distributed...

Ernst P. Stephan - Leibniz University, Hanover
Firstly, from [1] we consider a mixed formulation for an elliptic obstacle problem for a 2nd order operator and present an hp-FE interior penalty discontinous Galerkin (IPDG) method. The primal...

Dr. Stephen Maher - Zuse Institute Berlin, Germany
The tail assignment problem is a critical part of the airline planning process that is tasked with satisfying the operational constraints for all aircraft. The aim of this paper is to develop an ...
