Boeing Distinguished Colloquium and Seminar Lecture: Kenneth Golden, Oct 6th and 7th

Two lectures are being announced Thursday, October 6th and Friday, October 7th:

Anyone interested is invited to the Boeing Distinguished Colloquium this Thursday, October 6th, hosted by the Department of Applied Mathematics. Kenneth Golden will be here from the University of Utah to speak on “Modeling The Melt: What Math Tells Us About the Shrinking Polar Ice Caps.” His talk will be at 4 pm in Smith Hall 120, with the corresponding abstract and amazing polar expedition photos found below. A reception will follow in the Lewis Hall lounge.

There will also be a follow-up seminar talk, by Professor Golden, this Friday, October 7th. That talk, titled
“Homogenization for Sea Ice,” will take place at 11:30 am in Johnson Hall 175. The abstract is also found below.

Abstract for “Modeling The Melt: What Math Tells Us About the Shrinking Polar Ice Caps.”

The precipitous loss of Arctic sea ice has outpaced expert predictions. We will explore how mathematical models of composite
materials and statistical physics are being developed to study key sea ice structures and processes and advance how sea ice is
represented in climate models. Our composite material models for sea ice are developed in conjunction with field experiments that we
have conducted in both the Arctic and Antarctic. This work is helping to improve projections of the fate of Earth’s sea ice packs,
and the response of the polar ecosystems they support. The lecture is intended for a wide, interdisciplinary audience.

Abstract for “Homogenization for Sea Ice.”

The polar ice packs are critical indicators of climate change, as evidenced by the recent losses of Arctic sea ice. As a material, sea ice is a polycrystalline
composite of a pure ice matrix containing brine inclusions whose volume fraction and connectivity depend strongly on temperature. Fluid transport through the porous
microstructure of sea ice mediates key climatological and biological processes. We will discuss the development of mathematical models of composite materials and
statistical physics to describe the effective fluid, thermal, and electromagnetic
transport properties of sea ice, and to address other problems in sea ice physics
such as the evolution of melt ponds on the sea ice surface. We will cover a range
of mathematical topics, including percolation theory and critical behavior, forward and inverse homogenization, Stieltjes integral representations and bounds for effective transport coefficients, spectral measures, random matrix theory and
Anderson transitions, advection diffusion processes, and Ising models. In short, the mathematics and physics behind the Boeing Lecture on “Modeling the Melt” will be explored in more detail.
