Multigrid Method for Solving Poisson-Boltzmann Equation
, 2007 We present a first order accurate method for solving the partial differential equation, Poisson-Boltzmann Equation where the coefficients is assumed to be discontinuous across an interface and the source term is allowed to be a delta function.

Adaptive Algebraic Multigrid Methods [PDF]
, 2004 Our ability to simulate physical processes numerically is constrained by our ability to solve the resulting linear systems, prompting substantial research into the development of multiscale iterative methods capable of solving these linear systems with ...

Robust V-cycle multigrid method for anisotropic linear elasticity problems
四川大学学报. 自然科学版, 2019 A Robust V-cycle multigrid method is constructed for the linear system arising from the bilinear finite element discretization of anisotropic linear elasticity equations. By using the Xu-Zikatanov (XZ) identity, quasi-optimal convergence of the method is

OVERLAPPING MULTIGRID METHODS AS AN EFFICIENT APPROACH FOR SOLVING THE BLACK-SCHOLES EQUATION
Quantitative Methods in Economics, 2015 In this paper the modification of a two-level multigrid method by allowing an overlap between adjacent subdomains and its application to a one-dimensional Black-Scholes equation is described.

Algebraic Multigrid method of Kaczmarz method
, 2007 We are concerned with the algebraic multigrid (AMG) method for least square problem arisen from image restorations. We employ the Kaczmarz’s method as the smoothers for the AMG and prove the corresponding smoothing property.Abstract vii 1 Introduction 1 ...
