# 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.

In the second part of a two-part talk, we will be using the notion of generalised vector products to extend the framework of affine and projective rational trigonometries to three dimensions. Here,...

A/Prof. Hanlin Shang - Australian National University
This paper is concerned with forecasting probability density functions. Density functions are nonnegative and have a constrained integral, and thus do not constitute a vector space. Implementation of...

Philipp Guth - University of Mannheim, Germany
In this work we apply a quasi-Monte Carlo (QMC) method to an optimal control problem constrained by an elliptic partial differential equation (PDE) equipped with an uncertain diffusion coefficient. ...

Yusra Naqvi - University of Sydney
Many simplicial complexes which are important from a combinatorial, geometric or representation-theoretic perspective have enormous symmetry groups. Associated to the action of a group $G$ on a...

Leonard Cadilhac - Université de Caen Normandie
The problem of finding the best constant for Khintchine inequalities with Rademacher variables remained open for 50 years until Haagerup computed them in 1981. For free variables, the problem is...

John Steele and Bill McLean - UNSW Sydney
Details of Astra will be provided.

Rob Salomone - UNSW Sydney
For sampling from a log-concave density, we study implicit integrators resulting from theta-method discretization of the overdamped Langevin diffusion stochastic differential equation. Theoretical...

Anna Romanov - University of Sydney
Whittaker modules are certain representations of Lie algebras which were first studied by Kostant for their relationship to the Whittaker equation in number theory. From a representation-theoretic...

Fiona Johnson - UNSW Faculty of Engineering
Hydrological extremes by their very nature are rare events and requirecareful use of statistical methods to ensure robust and reliablepredictions. This presentation focuses on two case studies...

Houcein El Abdalaoui - University of Rouen
The Liouville function assigns the value $+1$ to $n$ if the number of prime factors of $n$ counted with multiplicities is even and $-1$ if not. The Möbius function coincides with the Liouville...
