# Seminar Archive - 2015

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.

Alexander Fish - University of Sydney
We present a new approach for establishing the recurrence of a set, through measure rigidity of associated action. Recall, that a subset $S$ of integers (or of another amenable group $G$) is...

Houying Zhu - UNSW Australia, School of Mathematics & Statistics
In this talk we consider an acceptance-rejection (AR) sampler based on deterministic driver sequences. We prove that the Kolmogorov-Smirnov distance (which coincides with the so-called star-...

Dr Shima Ghassempour - Western Sydney University, CMCRC Sydney
In every day life we often hear about obesity, smoking and chronic conditions and how they may affect our quality of life. But what do we know about their costs? Is it better to reduce obesity or...

Michael Feischl - UNSW
In this talk, we analyze adaptive mesh-refinement algorithms for finite element and boundary element discretizations of partial differential equations (PDEs). We introduce the concept of a posteriori...

Greg Markowsky - Monash University
The time it takes Brownian motion to leave a planar domain provides a method of measuring the size and shape of the domain. There a number of connections between this quantity and complex analysis,...

Christian Irrgeher - Johannes Kepler University Linz , Austria
To solve problems using simulation methods, like Monte Carlo (MC) or quasi-Monte Carlo (QMC) methods, it often requires to sample paths of stochastic processes which depend on Brownian motions....

Wadim Zudilin - University of Newcastle
It is a classical fact that the irrationality of a real number $x$ follows from the existence of a sequence $p_n/q_n$, with integral $p_n$ and $q_n$, such that $q_nx-p_n$ is nonzero for all $n$ and...

Timothy Trudgian - Australian National University
Take the Riemann zeta-function, $\zeta(s) = 1 + 2^{-s} + 3^{-s} + \ldots$, which converges whenever $\Re(s)>1$. Now chop the series after $N$ terms and call the finite piece $\zeta_{N}(s)$. In...

Sachi Srivastava - University of Delhi
We discuss L^p maximal regularity of second order Cauchy problems of the form     u''(t)+B(t)u'(t)+A(t)u(t)=f(t), t in [0,T),    u(0)=u'(0)=0. We also look at maximal regularity of the above problem...

Prof Richard Boys - Newcastle University (UK)
Ranking sportsmen whose careers took place in different eras is often a contentious issue and the topic of much debate. In this talk we focus on cricket and examine what conclusions may be drawn...
