An A Priori Error Analysis of the Local Discontinuous Galerkin Method for Elliptic Problems [PDF]
In this paper, we present the first a priori error analysis for the local discontinuous Galerkin (LDG) method for a model elliptic problem. For arbitrary meshes with hanging nodes and elements of various shapes, we show that, for stabilization parameters

Superconvergence of the local discontinuous Galerkin method for nonlinear convection-diffusion problems [PDF]
In this paper, we discuss the superconvergence of the local discontinuous Galerkin methods for nonlinear convection-diffusion equations. We prove that the numerical solution is ( k + 3 / 2 ) $(k+3/2)$ th-order superconvergent to a particular projection ...

An Optimized Schwarz Method for the Optical Response Model Discretized by HDG Method [PDF]
An optimized Schwarz domain decomposition method (DDM) for solving the local optical response model (LORM) is proposed in this paper. We introduce a hybridizable discontinuous Galerkin (HDG) scheme for the discretization of such a model problem based on ...

A Local Discontinuous Galerkin Method for KdV Type Equations
In this paper we develop a local discontinuous Galerkin method for solving KdV type equations containing third derivative terms in one and two space dimensions. The method is based on the framework of the discontinuous Galerkin method for conservation laws and the local discontinuous Galerkin method for viscous equations containing second derivatives ...

Supercloseness of the local discontinuous Galerkin method for a singularly perturbed convection-diffusion problem [PDF]
A singularly perturbed convection-diffusion problem posed on the unit square in $\mathbb{R}^2$, whose solution has exponential boundary layers, is solved numerically using the local discontinuous Galerkin (LDG) method with piecewise polynomials of degree

An oscillation free local discontinuous Galerkin method for nonlinear degenerate parabolic equations [PDF]
An oscillation free local discontinuous Galerkin (OFLDG) method is proposed for solving nonlinear degenerate parabolic equations. The damping terms are added to the original LDG scheme to control the spurious oscillations when solutions have a large ...

A discontinuous Galerkin method to solve Liouville’s equation of geometrical optics [PDF]
We present an alternative method to ray tracing that is based on a phase space description of light propagation. Liouville’s equation of geometrical optics describes the evolution of the basic luminance on phase space.

Local Discontinuous Galerkin Methods for the abcd Nonlinear Boussinesq System [PDF]
Boussinesq type equations have been widely studied to model the surface water wave. In this paper, we consider the abcd Boussinesq system which is a family of Boussinesq type equations including many well-known models such as the classical Boussinesq system, BBM-BBM system, Bona-Smith system etc.
