In this paper, we study the existence of a quasi solution to nonlinear inverse parabolic problem related to $$\aleph (u):\equiv u_{t}-\nabla \cdot (F(x,\nabla u))$$ℵ(u):≡ut-∇·(F(x,∇u)) where the function F is unknown. We consider a methodology, involving minimization of a least squares cost functional, to identify the unknown function F. At the first step of the methodology, we give a stability result corresponding to connectivity of F and u which leads to the continuity of the cost… CONTINUE READING
