Abstract

We consider the inverse boundary value problem of determining the potential q in the equation u + qu = 0 in Rn, from local Cauchy data. A result of global Lipschitz stability is obtained in dimension n 3 for potentials that are piecewise linear on a given partition of No sign, nor spectrum condition on q is assumed, hence our treatment encompasses the reduced wave equation u + k2c -2u = 0 at fixed frequency k.
