## The math of swarming robots, superconductors, and slime mold

Monday, June 26, 5:30 pm

**Abstract:**Systems of interacting agents arise throughout the natural world and are studied in such varied disciplines as engineering, physics, and biology. What is the optimal way for a swarm of robotic bees to pollinate a bed of crops? How can we use vortex motion in superconductors to develop new technologies for renewable energy? How does a colony of slime mold communicate using chemical signals? Prof. Katy Craig will describe the mathematics underlying systems of interacting agents and how such systems can be analyzed using an age old scientific technique: what happens if we poke it?

**Title: **Towards an Atomistic Theory of Heat

**Location: **South Hall 6635

At the macroscopic scales it intuitively makes sense to talk about the temperature at a point, but when one zooms into the scale of individual atoms, the definition of local temperature breaks down. In this talk I will discuss my research in collaboration of Carlos and Xiantao Li at Penn State where we attempt to define and model temperature at the atomistic level.

**Title:** Modeling Populations of Adaptive Individuals

"...How do we model a population of individuals that all make tradeoff decisions, when the options and payoffs available to each individual depends on the behavior of all the other individuals? We have explored one solution, which is to model individual decisions as approximations, based explicitly on simple predictions, that produce good but not optimal behavior and are updated routinely as the world changes."
