Colloquium

Geometry and topology of random curves

Igor Rivin - Temple University  (Host: Victor Moll)

Abstract:

We study (experimentally and theoretically) random curves (in many senses) in space and in the plane, including such of their properties as the knot type.

Probability and Statistics

Diffusion-Limited Annihilating Systems

Matthew Junge - Duke University

Abstract:

We study a two-type annihilating system in which particles are placed with equal density on the integer lattice. Particles perform simple random walk and annihilate when they contact a particle of different type. The occupation probability of the origin was known to exhibit anomalous behavior in low-dimension when particles have equal speeds. Describing the setting with asymmetric speeds has been open for over 20 years. We prove a lower bound that matches physicists' conjectures and discuss partial progress towards an upper bound. Joint with Michael Damron, Hanbaek Lyu, Tobias Johnson, and David Sivakoff.

Simulations of Pulsating Soft Corals

Shilpa Khatri - UC Merced

Abstract:

Soft corals of the family Xeniidae have a pulsating motion, a behavior not observed in many other sessile organisms. We are studying how this behavior may give these coral a competitive advantage. We will present direct numerical simulations of the pulsations of the coral and the resulting fluid flow by solving the Navier-Stokes equations coupled with the immersed boundary method. Furthermore, parameter sweeps studying the resulting fluid flow will be discussed.

Woman mathematician of interest:  Anna-Karin Tornberg.

Combinatorial structures and invariants through algebraic lenses

Tai Ha - Tulane University

Abstract:

We shall discuss how to use algebraic formulations to approach and understand a number of problems in linear programming and graph theory. Particularly, we shall examine the (integral) optimal solutions to system of linear constraints, and important invariants in graph theory, such as the chromatic, matching and covering numbers.
