Christian de Nicola Larsen - UNSW Sydney
The Gelfand Duality is an equivalence of categories between the category of commutative unital C*-algebras and the category of compact Hausdorff spaces. The talk will cover this equivalence of...

Mitchell Roberts - UNSW Sydney
In 1960 Eugene Wigner wrote The Unreasonable Effectiveness of Mathematics in the Natural Sciences, an essay questioning the role of mathematics in the physical sciences, and especially questioning...

Ryan Snoyman - UNSW Sydney
Abstract: As quantum computers continue to increase in size, an efficient proof of quantumness is required to certify that they are performing computations as expected. In this talk, we examine a...

Vida Dujmović - University of Ottawa
I will talk about product structure theory of graphs and its application to various problems such as: graph adjacency encoding, queue/stack number and graph colourings.

Gérald Tenenbaum - Université de Lorraine
Let $\varrho$ be a complex number and let $f$ be a multiplicative arithmetic function whose Dirichlet series takes the form $\zeta(s)^\varrho G(s)$, where $\zeta(s)$ is the Riemann zeta function and...

Craig H. Bishop - School of Earth Sciences and ARC Centre of Excellence for Climate Extremes, University of Melbourne
Current state estimation or data assimilation techniques assume Gaussian uncertainties for both forecasts and observations. However, unbiased observations of bounded variables can be shown to have...

Dominic Palanca - UNSW Sydney
In this talk we will present an original result connecting the convolution of harmonic polynomials (those satisfying Laplace’s equation) to a certain algebra of symmetric tensors. Although the result...

Wenbo Wu & Jörn Callies - Division of Geological and Planetary Sciences, California Institute of Technology
More than 90% of the energy trapped on Earth by increasingly abundant greenhouse gases is absorbed by the ocean. Monitoring the resulting ocean warming remains a challenging sampling problem. To...

David Morris - UNSW Sydney
The Polynomial Learning with Errors problem (PLWE) is a promising contender for lattice based, post quantum cryptography, with applications revolving around the security and implementation of Public...

Yudhistira A Bunjamin PhD Candidate - UNSW Sydney
For over two years now, various members of the school have worked together on designing mathematics outreach workshops for primary and secondary school students, motivated by promoting mathematical...
