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.

Patrick Laub - The University of Queensland
We consider the general problem of estimating probabilities which arise as a union of dependent events. We propose a flexible series of estimators for such probabilities, and describe variance...

Daniel Altman - University of New South Wales
Consider the problem of factorising a degree n polynomial over F_p. Randomised algorithms whose complexities are polynomial in n and log p date back half a century. The salient open problem in the...

Professor David Stewart - University of Iowa
Dynamics and differential equations that involve inequalities arise where there are hard constraints, such as in mechanical impact, ideal diodes in electrical circuits, and traffic networks....

Shinnosuke Okawa - Osaka University
Bounded derived category of coherent sheaves of an algebraic variety is a relatively new but very important invariant. There are examples of non-singular projective varieties $X$ and $Y$ which have...

Joshua Capel, Daniel Mansfield and Norman Wildberger - School of Mathematics and Statistics, UNSW SYDNEY
OpenLearning is an Australia MOOC provider that was set up by UNSW students together with Prof. Richard Buckland, and has now spread internationally with close to 4000 courses. It has recently been...

Matt Wand - University of Technology Sydney
We explain how the notion of message passing can be used to streamline the algebra and computer coding for fast approximate inference in large Bayesian statistical models. In particular, this...

Ruth Corran - The American University of Paris
I will speak about joint work with Michel Broué and Jean Michel (https://arxiv.org/abs/1704.03779) which is motivated by questions coming from theSpetses project. For $G$  a (complex) reflection...

Dmitri Nikshych - University of New Hampshire
A classical theorem of Joyal and Street establishes an equivalence between braided categorical groups and quadratic forms.  This  brings an important geometric insight into the theory of braided...

James Hortle - UNSW Mathematics and Statistics
In this talk we discuss the potential of two machine learning techniques (support vector machines and neural networks) in aiding medical diagnosis of Alzheimer's disease. In particular, we see...

Christopher Rock - UNSW Mathematics and Statistics
Four-dimensional cone beam computed tomography (4D CBCT) is a medical imaging technology used in diagnosing and visualising lung cancer, and is used as part of radiotherapy. 4D CBCT scanners capable...
