Carleman estimate for complex second order elliptic operators with discontinuous Lipschitz coefficients

Analysis of PDEs 2020-01-14 v1

Abstract

In this paper, we derive a local Carleman estimate for the complex second order elliptic operator with Lipschitz coefficients having jump discontinuities. Combing the result in [BL] and the arguments in [DcFLVW], we present an elementary method to derive the Carleman estimate under the optimal regularity assumption on the coefficients.
