| contents | We consider the inverse problem of the simultaneous identification of the coefficients $σ$ and $q$ of the equation div$(σ\nabla u) + qu=0$ from the knowledge of the complete Cauchy data pairs. We assume that $σ=γA$ where $A$ is a given matrix function and $γ, q$ are unknown piecewise affine scalar functions. No sign, nor spectrum condition on $q$ is assumed. We derive a result of global Lipschitz stability in dimension $n\geq 3$. The proof relies on the method of singular solutions and on the quantitative estimates of unique continuation. |
