Abstract:
Abstract. In this talk I will present a recent result showing that linear combinations of tensor products of k gradients of harmonic functions, with k at least three, are dense in C_0^infty(\Omega), for any bounded domain \Omega in dimension 3 or higher. This kind of density result has applications to inverse problems for elliptic quasilinear equations/systems in divergence form, where the nonlinear part of the ”conductivity is anisotropic.Download:Talk_1120919.jpg
