Propagation of smallness for an elliptic PDE with piecewise Lipschitz coefficients
Cătălin I. Cârstea, Jenn-Nan Wang
In this paper we derive a propagation of smallness result for a scalar second elliptic equation in divergence form whose leading order coefficients are Lipschitz continuous on two…

Uniqueness for the inverse boundary value problem of piecewise homogeneous anisotropic elasticity in the time domain
Cătălin I. Cârstea, Gen Nakamura, Lauri Oksanen
We consider the inverse boundary value problem of recovering piecewise homogeneous elastic tensor and piecewise homogeneous mass density from a localized lateral Dirichlet-to-Neuma…
