Our regular seminar program covers a broad range of topics from applied mathematics, pure mathematics and statistics. All staff and students are welcome. This page has a complete list of past seminars and a list restricted by year can be accessed via the left-hand menu.

James A. Nichols - Laboratoire Jacques-Louis Lions, UPMC, Sorbonnes Universités, Paris, France
Reduced (or surrogate) modelling replaces a high-resolution PDE model with some simple model that only loses some small and known accuracy. Reduced models are designed to allow for fast or closed-...

Prof Torsten Linß - FernUniversität in Hagen, Germany
In this lecture singularly perturbed linear reaction-diffusion problems in one and two dimensions are considered. These are elliptic equations that change character when the perturbation parameter...

A. Prohl - University of Tuebingen, Germany
I discuss the optimal control via an exterior field of a ferromagnetic chain immersed into a heat bath. For its numerical realization, I compare an approach which rests on Pontryagin’s maximum...

Bishnu Lamichhane - University of Newcastle
In this talk we will briefly introduce the mixed finite element method and show its applications. We start with a simple mixed formulation for the Poisson problem and then consider different mixed...

Debopriya Mukherjee - UNSW, Sydney.
I will discuss about the existence of a solution to an optimal relaxed control problem for the linearly-coupled viscoelastic Oldroyd-B model driven by Levy noise. Then, the existence and uniqueness...

Pierre L'Ecuyer - Universite de Montreal, Canada
Randomized quasi-Monte Carlo (RQMC) is commonly used to estimate the mathematical expectation of a random variable expressed as an integral over the $s$-dimensional unit cube $(0, 1)^s$. Under...

Professor Hwa-Lung Yu - National Taiwan University
The rapid development and increase of low-cost sensors provide an unprecedented new way in understanding the space-time distribution of environmental quality. However, due to the relative low quality...

Michael Feischl - UNSW, Sydney.
We present the idea of multi-index Monte Carlo methods in the frame of  PDEs with random coefficients. We show error estimates and prove that the multi-index approach can be more efficient than the...

Prof Ernst P Stephan - Leibniz Universitat Hannover
We present h and p-versions of the time domain boundary element method for boundary and screen problems for the wave equation in R^3. First, graded meshes are shown to recover optimal...

Jiwei Zhang - Beijing Computational Science Research Center
We consider the simulation of nonlocal wave propagation in an unbounded multi-scale medium. In particular, we discuss (a) the design of artificial/absorbing boundary conditions (ABCs); (b) the...
