Reconstruction from boundary measurements for less regular conductivities
In this paper, following Nachman's idea  and Haberman and Tataru's idea , we reconstruct $C^1$ conductivity $\gamma$ or Lipchitz conductivity $\gamma$ with small enough value of $|\nabla log\gamma|$ in a Lipschitz ...
Discreteness of transmission eigenvalues for higher-order main terms and perturbations
In this paper we extend Sylvester's approach via upper triangular compact operators to establish the discreteness of transmission eigenvalues for higher-order main terms and higher-order perturbations. The coefficients of ...
