Lipschitz continuous dependence of piecewise constant Lamé coefficients from boundary data: the case of non flat interfaces (1406.1899v1)

Published 7 Jun 2014 in math.AP

Abstract: We consider the inverse problem of determining the Lam\'e moduli for a piecewise constant elasticity tensor ${\mathbb C}= \sum_{j} {\mathbb C}j \chi{D_j}$, where ${D_j}$ is a known finite partition of the body $\Omega$, from the Dirichlet-to-Neumann map. We prove that Lipschitz stability estimates can be derived under $C{1,\alpha}$ regularity assumptions on the interfaces.
