Seminar Archive - 2017

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

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...

Prof. Thorsten Koch - Technische Universitaet (TU) and Zuse Institute Berlin (ZIB)
The Steiner tree problem in graphs is a classical problem that commonly arises in practical applications as one of many variants. While often a strong relationship between different Steiner tree...

Nassif A Ghoussoub - University of British Columbia
One of the best kept secrets about mathematicians is that we are often at the tip of the spear in the struggle for social/political causes. We are inspired by the mathematical hell raisers of...

Peter Kim - University of Sydney
Human post-menopausal longevity makes us unique among primates, but how did it evolve? One explanation, the Grandmother Hypothesis, proposes that as grasslands spread in ancient Africa displacing...

Prof Søren Asmussen - Aarhus University
Monte Carlo simulation can be viewed as a vehicle for performing computer experiments with randomness in problems that are too complex or too difficult to allow for theoretical calculations. We give...

Simon Macourt - UNSW
We provide a background on some recent results on multilinear exponential sums as well as collinear triples over a finite field. We then focus on the specific cases of weighted trilinear and...

Liangyi Zhao - UNSW
Borrowing a line from an anarchist and mangling it somewhat: happy family members are all alike.  Indeed, the objects of interest of this talk will be families consisting of kindred members having...

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...

Johann Makowsky - Technion – Israel Institute of Technology
A. Mani and R. Stones in their paper from 2016 study the sequence of integers $tc_{a,b}(n) = T(K_n,a,b)$, where $T(G,X,Y)$ is the Tutte polynomial and $a,b \in \mathbb{Z}$. For the case $a=1$ this...

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...
