Numerical Methods for a One-Dimensional Interface Separating Compressible and Incompressible Flows
TL;DR: 1D numerical methods for treating an interface separating a liquid drop and a high speed gas flow and has direct, although algorithmically complicated, extensions to 2nd and 3rd order Runge Kutta methods.
Journal ArticleDOI
Density matrix minimization with $\ell_1$ regularization
TL;DR: In this article, a convex variational principle is proposed to find sparse representation of low-lying eigenspace of symmetric matrices, which corresponds to a sparse density matrix minimization algorithm with $\ell_1$ regularization.
Triangle based TVD schemes for hyperbolic conservation laws
TL;DR: In this article, a triangle-based total variation diminishing (TVD) scheme for the numerical approximation of hyperbolic conservation laws in two space dimensions is constructed, which is accomplished via a nearest neighbor linear interpolation followed by a slope limiting procedures.
Journal ArticleDOI
Sparse Recovery via Differential Inclusions
TL;DR: In this article, Bregman dynamics are used to solve nonlinear differential inclusions, which is based on the notion of inverse scale space (ISS) developed in applied mathematics, and their solution paths are regularization paths better than the LASSO regularization path.

Fast Linearized Bregman Iteration for Compressive Sensing and Sparse Denoising
TL;DR: In this paper, the authors proposed an extremely fast, efficient, and simple method for solving the problem:min{parallel to u parallel to(1) : Au = f, u is an element of R-n}.
