Our next talk will be this Thursday October 4th in BA 2135 at 6:00.

Prof. Almut Burchard is presenting on

A shape optimization problem related with flocking

Abstract:

Given a large number of particles where each pair

experiences a force determined by their distance.

When can a flock form, and what should it look like?

Suppose that any two particles attract when they are

far apart, and repel each other when they are close. One

may conjecture that a sufficiently large number of

particles would organize itself in a round flock; if the

number of particles is too small, they would disperse. I will

describe recent progress towards this conjecture,

and mention open problems.
