• Spectral Methods for Periodic Initial Value Problems with Nonsmooth Data

  سند علمی۱۹۹۳PRAVIR K. DUTT, A. K. SINGH, P. K. DUTT

  In this paper we consider hyperbolic initial value problems subject to periodic boundary conditions with nonsmooth data. We show that if we filter the data and solve the problem by the Galerkin-Collocation method, recently proposed by us, then we can recover pointwise values with

• On the Spectral Deferred Correction of Splitting Methods for Initial Value Problems

  سند علمی۲۰۰۶THOMAS HAGSTROM, RUHAI ZHOU

  Spectral deferred correction is a flexible technique for constructing high-order, stiffly-stable time integrators using a low order method as a base scheme. Here we examine their use in conjunction with splitting methods to solve initial-boundary value problems for partial differ
