Hyperbolicity-Preserving Stochastic Galerkin Methods for Conservation Laws Based on Associative Truncated Products on Polynomial Spaces

Haroun Meghaichi, Yulong Xing

Stochastic Galerkin discretizations of nonlinear hyperbolic conservation laws may lose hyperbolicity because the standard pseudospectral product is generally nonassociative, leadin…

A Priori Error Analysis of a High-Order Selective Discontinuous Galerkin Method for Elliptic Interface Problems

Fang Liu, Haroun Meghaichi, Xu Zhang

This paper develops a high-order selective discontinuous Galerkin (SDG) method for solving elliptic interface problems on interface-unfitted Cartesian meshes. This method applies t…

A unified immersed finite element error analysis for one-dimensional interface problems

Slimane Adjerid, Tao Lin, Haroun Meghaichi

It has been noted that the traditional scaling argument cannot be directly applied to the error analysis of immersed finite elements (IFE) because, in general, the spaces on the re…
