*Professor Tom Salisbury - York University, Toronto, Canada*

Random walk in random environment is a model for motion through a disordered medium. Traditionally this is studied with fairly strong non-degeneracy conditions on the environment. I'll describe some...

*Jan Nyquist Roksvold - University of Tromsø*

Let C be a linear code over the field F_q. This code may be extended to a code C' over F_Q, where Q=q^m. Let A(Q)_i be the number of words in C' of weight i, and let M(C) be the vector matroid...

*Bruno Iochum - Aix-Marseille University and CNRS*

The purpose is to present a survey (no details) within the noncommutative geometry framework of Connes on two different approaches for manifolds with boundaries. The objective is to construct...

*Professor Richard Davis - Columbia University, New York*

n this paper we give an asymptotic theory for the eigenvalues of the sample covariance matrix of a multivariate time series when the number of components p goes to infinity with the sample size. The...

*Oded Yacobi - University of Sydney*

A common theme in modern representation theory is to study the representations of quantisations of symplectic varieties. Lie theory can be formulated in this language using the Springer resolution...

*Jan Rozendaal - Delft University of Technology*

Let G be a locally compact group acting on a measure space (X,mu), where the measure mu is G-invariant. Then G acts unitarily on L^{2}(X,mu) and conditions are known that allow one to decompose the...

*Emi Tanaka - University of Wollongong*

Regulatory proteins bind to certain sites of the DNA to regulate the transcription of a protein, thus characterising these binding sites is of a great interest to the bioinformatics community. Motif...

*Francois Ledrappier - University of Notre Dame*

We consider the stochastic entropy for the Brownian motion on the universal cover of a compact Riemannian manifold M. We discuss the relation with the other global invariants, the rigidity if M has...

*Yu Guang Wang - School of Mathematics and Statistics, UNSW*

Isotropic random fields on the sphere have applications in environmental models and astrophysics. The classic Karhunen-Lo\`{e}ve expansion in terms of spherical harmonics has a drawback of requiring...

*Alina Ostafe - UNSW*

Algebraic Dynamical Systems over finite fields, that is, dynamical systems generated by iterations of polynomials and rational functions, are exciting and challenging mathematical objects with...
