SUMMARY:Carleman estimate for Zaremba boundary condition - Robbiano\, L (U
 niversit de Versailles Saint-Quentin-en-Yvelines)

CONTACT:Mustapha Amrani
DESCRIPTION:The Zaremba boundary condition is a mixed boundary condition o
 f the following type\, on a part of the boundary we impose Dirichlet bound
 ary condition and on the other part we impose the Neumann boundary conditi
 on. For such a problem we prove an logarithme type estimate for the decrea
 se of energy of a solution for a damped wave equation. In the talk we shal
 l explain the plan of the proof. The main part is to prove a Carleman esti
 mate in a neighborhood of the boundary where the type of boundary conditio
 ns changes.\n
