Identification of discontinuous coefficients in elliptic problems using total variation regularization

Identification of discontinuous coefficients in elliptic problems using total variation regularization

We propose several formulations for recovering discontinuous coefficients in elliptic problems by using total variation (TV) regularization. The motivation for using TV is its well-established ability to recover sharp discontinuities. We employ an augmented Lagrangian variational formulation for sol...
