In hybrid regularization,we build a Krylov subspace and compute approximate solutions by regularizing the linear system projected on the Krylov subspace.
Krylov subspace recycling is useful for solving a sequence of slowly changing linear systems.It has been shown that recycled GMRES usually cannot be used in
Finite element discretisation of the Dirichlet biharmonic problem by Bogner-Fox-Schmit(bicubic Hermite)elements leads to a symmetric positive definite coeff
The solution of large sparse linear systems are at the core of most problems in science and engineering.Iterative methods,in conjunction with the use of pre
In this talk we present an h-adaptive Runge-Kutta discontinuous Galerkin(RKDG)method for the Vlasov-Poisson system.A simple adaptive strategy is designed ba
We present a novel high order discontinuous Galerkin finite element method on space-time adaptive Cartesian meshes(AMR)for hyperbolic conservation laws in m
Time integration methods involving the matrix exponential are attractive for time domain photonic crystal modeling due to their excellent stability and accu
