International Day of Mathematics 2023 Public Lectures at ���������¼� Sydney

Join us for these special lectures by two Applied Mathematicians at ���������¼� Sydney. We will hear presentations from:

Michael Denes, who won the 2022 TM Cherry Prize for the best student talk at the ANZIAM Annual Conference, recently completed his PhD in Applied Mathematics at ���������¼�.

Frances Kuo��is a Professor in Applied Mathematics at ���������¼� who has won prestigious awards for her research, and has delivered several invited plenary talks at conferences across the globe.

From ocean waves to mesoscale eddies, Michael Denes

The global ocean isn't a stagnant pond, rather, it's a big bowl of turbulent soup! It's in constant motion, distributing heat, salt, carbon, and other climate-relevant properties around the world. It's strongly influenced by stratification and rotation, and is organised by a number of dynamical features on a range of spatial and temporal scales, from rip currents at the human scale to the great ocean conveyer belt at the planetary scale. At each scale, the corresponding features organise the turbulence and provide a schematic for the general ocean flow. Many of these features are transient in nature, so identifying and tracking these features, and ultimately quantifying their contribution to ocean mixing and climate processes, is challenging. I'll begin this talk by describing my journey in maths and approach to mathematical research. I will then discuss some of my exciting results from recent studies on transport and mixing problems related to ocean eddies and Southern Ocean fronts.

Lifting the curse of dimensionality, Frances Kuo

High dimensional computation with very many or even infinitely many variables is a new frontier in scientific computing, with applications ranging from financial mathematics to groundwater flow, neutron transport, wave propagation and more. Often the dimensionality arises from uncertainty or randomness in the data. High dimensional problems pose immense challenges because of a nearly inevitable tendency for the cost of computation to grow exponentially with dimension. This talk is a tale on how “Quasi-Monte Carlo” methods can be used to lift this curse of dimensionality.

The lectures will be presented in Room 4082 in the Red Centre building (ref: ).

Drinks and finger food will be hosted following the talks, in Red Centre Room 3082 (ref: ).��
