Wave and Maxwell Equations in the Neighborhood of Corners

10:15 AM-12:15 PM
Room 244

This minisymposium addresses various problems in solving wave and Maxwell equations in the neighborhood of corners. The speakers will discuss theoretical and numerical issues including diffraction-type behavior and singular-type behavior.

Organizer: Olivier D. Lafitte
Commissariat a l'Energie Atomique and ENS Cachan, France
