SUMMARY:Joint works on Continuous solutions to a balance equation - Dr Lau
 ra Caravenna\, University of Oxford

CONTACT:CCA
DESCRIPTION:The talk is concerned with continuous solutions to a scalar\, 
 1D balance law having bounded source term. We will discuss the corresponde
 nce between Eulerian and Lagrangian formulation\, mostly focusing on the s
 imple equation u_t+[u2/2]_x=g with g bounded and assuming u continuous but
  neither Sobolev nor BV. This is strictly related to a characterization of
  intrinsic Lipschitz graphs in the sub-Riemannian Heisenberg groups\, afte
 r the characterization which had already been given of intrinsic regular g
 raphs. The talk will be mainly based on collaborations with G. Alberti\, S
 . Bianchini\, F. Bigolin\, F. Serra Cassano.
