#### Perturbations of finite dimensional C*-algebras

###### F. Bocca (UIUC)

3:00 pm in 3405 Siebel Center,Monday, February 6, 2006

#### How to Catch the Bad Guy

###### R. Ghrist   [email] (UIUC Math)

Abstract: This talk describes a new approach to pursuit-evasion games where one or more pursuers try to catch one or more evaders. Most of the known results come from differential equations or computational geometry and apply to Euclidean domains which are either planar and/or convex. This talk will introduce methods from comparison geometry which apply to non-convex domains of arbitrary dimension which satisfy a type of metric curvature constratint (cat(0) spaces). This talk will be at an elementary level and require no background in either differential games or cat(0) geometry.

3:00 pm in 343 Altgeld Hall,Monday, February 6, 2006

#### Representations of the Poincare Group and Introduction to Relativisitic Quantum Field Theory

###### Richard Corrado & Sheldon Katz (UIUC Physics and Math)

Abstract: Richard Corrado will start by wrapping up last week's discussion of the Poincare group, its representations, and their physical interpretation. Then Sheldon Katz will begin relativistic field theory with the theory of a scalar field.
