Seminar Archive - 2019

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.

Christopher Drovandi - Queensland University of Technology
Approximate Bayesian computation (ABC) is the standard method for performing Bayesian inference in the presence of a computationally intractable likelihood function. ABC proceeds by comparing the...

Imke Botha - Queensland University of Technology
Parameter inference for stochastic differential equation mixed effects models (SDEMEMs) is a challenging problem. Analytical solutions for these models are rarely available, which means thatthe...

Alireza Amini Harandi - University of Isfahan
In this talk, we will discuss some fundamental problems in metric fixed point theory that have been solved and other questions that remain open. The talk will be largely expository.

Nina Kamcev - Monash University
A subset S of initially infected vertices of a graph G is called forcing if we can infect the entire graph by iteratively applying the following process. At each step, any infected vertex which has a...

Michael Betancourt - Symplectomorphic, LLC
Despite the promise of big data, inferences are often limited not by sample size but rather by systematic effects.  Only by carefully modeling these effects can we take full advantage of the data --...

Gurvan Madec - LOCEAN-IPSL, CNRS / Université P. et M. Curie, Paris, France
  The Southern Ocean connects the Indian, Pacific and Atlantic Oceans and provides a direct pathway to exchange mass, heat and salt across the World Ocean, therefore playing an important role in the...

Kevin McGown - California State University, Chico
The class number is among the most important invariants associated to a number field. Conjecturally, its behavior (at the “good” primes) is governed by the heuristics of Cohen-Lenstra-Martinet. By...

Mark Watkins - University of Sydney
Gauss conjectured there are exactly nine imaginary quadratic fields with class number one (i.e., unique factorization). This was proven by independent work of Heegner, Baker, and Stark. By now, there...

Prof Norman Wildberger - UNSW
Archimedes’ famous determination of the relation between a parabolic arc and the area of a maximally inscribed triangle, involving the factor 4/3, is the earliest computation in Calculus. It reveals...

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-...
