## 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:*Fluvial Landscapes: The Next Generation

*Location:*South Hall 6635

The Smith and Bretherton model is a family of partial differential equations that model the transport-limited case of erosion. With the use of appropriate numerical schemes, simulations of these equations contain large and small scale dynamics crucial to the validity of the model. Even with modern processing power and parallelism, these simulations take a significantly long time to run. In this talk I will discuss these necessary scaling dynamics, the numerical schemes used to simulate these equations, some minor changes that were made to the numerics to accelerate computations, methods to "artificially" generate these eroded surfaces, and how these artificial surfaces altered our understanding of the small scale dynamics.
