Bryce Kerr - UNSW Canberra
In this talk we describe some progress to a conjecture of Zhao on the distribution of fractions with power denominator in short intervals. In particular we show how one may obtain an averaged form of...

Scott Maxwell - Director Digital Innovation, Information Gateways
Background: Ed is an innovative digital learning platform designed by an Australian team. Some standout features of Ed (https://edstem.org) - Ed Sway: Live in-class quizzes and polls to increase...

Bill McLean - School of Mathematics and Statistics, UNSW
This talk is an overview of the discontinous Galerkin (DG) method as a time-stepping procedure for classical and fractional diffusion problems. After motivating the definition of the procedure, I...

Prof N J Wildberger - UNSW Sydney
The most important 20th century development in the theory of curves and surfaces was initiated by two French car engineers around 1960. The quadratic and cubic curves they introduced, with further...

Anne Thomas - University of Sydney
The notion of divergence of geodesics was introduced by Gromov in the 1980s as a way of quantifying how fast a pair of geodesic rays in a space move away from each other.  Gersten then used this idea...

Ágnes Cseh - Hungarian Academy of Sciences
Our input is a complete graph $G=(V,E)$ on $n$ vertices where each vertex has a strict ranking of all other vertices in $G$. Our goal is to construct a matching in $G$ that is popular. A matching $M... Dr Daniel Mansfield - UNSW Sydney We discuss Si.427 from the Istanbul Archeological Museum, which was recently discovered to be one of the most complete examples of applied geometry from the ancient world, and demonstrates that... Jorge Mello - University of New South Wales A famous integrality result due to Siegel says that genus one curves have a finite number of integral Solutions. In this talk we will recall some analogous results in the context of arithmetic... Faezeh Alizadeh - Shahid Rajaee Teacher Training University, Iran; and University of Western Australia Let$F$be a field and$F^{r \times s}$denote the space of$r \times s$matrices over$F$. Let$K$be an extension of$F$. Given matrices$A$in$K^{r \times r}$and$B$in$K^{s \times s}\$ we call...

Michael Stewart - University of Sydney
We report on recent progress in ongoing work, jointly with Professor Alan Welsh of ANU, on inference concerning scale parameters of latent distributions in random effect models. An overarching...
