*Dr Pavel Krivitsky - University of Wollongong*

Egocentric network sampling observes the network of interest from the point of view of a set of sampled actors, who provide information about themselves and anonymized information on their network...

*Randell Heyman - UNSW*

The approximate GCD problem seeks to efficiently determine the GCD of a set of numbers.We do not know most or all of the numbers; rather we are given numbers that lie close by.As well as discussing...

*Prof. Mary Myerscough - The University of Sydney*

Why do some people develop cardiovascular disease while others with similar risk profiles do not? What causes plaques to regress? Why does raising HDL (“good cholesterol”) reduce cardiovascular...

*Guoyin Li - University of New South Wales*

Optimization problems involving polynomial functions are of great importance in applied mathematics and engineering, and they are intrinsically hard problems. They arise in important engineering...

*Dr Peter Exterkate - University of Sydney*

Kernel ridge regression is a technique to perform ridge regression with a potentially infinite number of nonlinear transformations of the independent variables as regressors. This makes it a powerful...

*Anna Tomskova - UNSW*

Let M be a von Neumann algebra and let (L_p(M), ||.||_p), 1<=p<infinity be Haagerup's L_p-space on M. It is proved that the differentiability properties of ||.||_p are precisely the same as...

*Hendrik Grundling - UNSW*

We consider group actions a:G->A of topological groups on C*-algebras A of the type which occur in many quantum physics models. These are singular actions in the sense that they need not be...

*Edward McDonald - School of Mathematics and Statistics*

In 1994 Alain Connes introduced a ``quantised" calculus, based on operator theoretic expressions which play roles analogous to derivatives and differentials in ordinary calculus. Quantised calculus...

*Dr Anbupalam Thalamuthu, Assoc/Prof Wei Wen - Centre for Healthy Brain Ageing (CHeBA), School of Psychiatry, UNSW Medicine*

CHeBA aims to conduct multidisciplinary research into ageing in health and disease, and be involved in knowledge dissemination and translational research. See http://cheba.unsw.edu.au/ for details....

*Prof. Mark Freidlin - University of Maryland*

Long time behavior of a dynamical system, evolutionary PDE, or a stochastic process, under certain assumptions, can be described by the invariant measure corresponding to the initial condition...
