DESCRIPTION:Title: Some non-uniqueness results in the Calderon inverse prob
 lem with local or disjoint data\n	Abstract: In dimension 3 or higher\, the 
 anisotropic Calderon inverse problem amounts to recovering a Riemannian me
 tric on a compact connected manifold with boundary from the knowledge of t
 he Dirichlet to Neumann operator (modulo diffeomorphisms that fix the boun
 dary). In this talk\, I will prove that there is non uniqueness in the Cal
 deron problem when : 1) the Dirichlet and Neumann data are measured on the
  same proper subset of the boundary provided the metric is only Holder con
 tinuous. 2) the Dirichlet and Neumann data are measured on distinct subset
 s of the boundary (for smooth metrics). This is a joint work with N. Kamra
 n (9IÖÆ×÷³§Ãâ·Ñ) and F. Nicoleau (Nantes).\n	\n	\n	 \n
