1. Domain Decomposition and Preconditioned Iterative Methods for the Helmholtz Equation
Abstract : New preconditioned iterative solution methods for the Helmholtz equation are constructed. To evaluate the performance of the methods, two-dimensional problems with a waveguide geometry are used as model problems. Second- and fourth-order accurate finite difference discretizations are used. READ MORE

2. Oversampled radial basis function methods for solving partial differential equations
Abstract : Partial differential equations (PDEs) describe complex real-world phenomena such as weather dynamics, object deformations, financial trading prices, and fluid-structure interaction. The solutions of PDEs are commonly used to enhance the understanding of these phenomena and also as leverage to make technological improvements to consumer products. READ MORE
