*Kirsten Vo-Phuoc - UNSW*

Gauge theories are the underpinning theories that we use to understand the fundamental forces and how they interact with particles. Originally constructed under physical concepts and notation and now...

*Nicholas Bouzanis - UNSW*

In this talk I present some basic results on double operator integrals in the finite dimensional setting using matrices. We then see a result proved by Alan Mcintosh in his paper "Counterexample to a...

*Steve Siu - UNSW*

Often given a topological space one can assign to it an algebraic invariant which gives us information on the space. One well known example is the fundamental group. In this talk I will present...

*Peter Ayre - UNSW*

Nearly half a century ago M.G. Krein made an elusive conjecture on the behaviour of operator-valued Lipschitz functions. It was only very recently that a resolution to his conjecture was found in the...

*Matt Wand - University of Technology, Sydney*

Semiparametric regression is an extension of regression that permits incorporation of flexible functional relationshipsusing basis functions, such as splines and wavelets, and penalties and is now...

*Ken Dykema - Texas A&M University*

In classical matrix theory, a matrix can be written in upper triangular form with help of its invariant subspaces. A similar result, due to Ringrose in 1962, holds for compact operators on infinite...

*Richard A. Davis - Columbia University*

This paper studies theory and inference related to a class of time series models that incorporates nonlinear dynamics. It is assumed that the observations follow a one-parameter exponential family of...

*Michael Whittaker - University of Wollongong*

A self-similar action (G,X) consists of a group G along with a self-similar action of the group on a rooted tree. Self-similarity is displayed by the action of the group acting on all levels of the...

*Domingo Gomez-Perez - University of Cantabria, Spain*

Pseudorandom sequences are used in many fields such that simulation, cryptography, etc. Normally, they are assocciated with a Monte Carlo rule, where the elements of the sequence should "appear" to...

*Robert Coquereaux - CNRS*

Using representation theory of affine Lie algebras, or of quantum groups at
roots of unity, one constructs modular fusion categories that have been used for quite a
while in various fields of...
