RT info:eu-repo/semantics/article T1 Spectral discretizations analysis with time strong stability preserving properties for pseudo-parabolic models A1 Abreu, Eduardo A1 Durán Martín, Ángel K1 Pseudo-parabolic equations K1 Spectral methods K1 Error estimates K1 Strong stability preserving methods K1 Non-regular data AB In this work, we study the numerical approximation of the initial-boundary-value problem of nonlinear pseudo-parabolic equations with Dirichlet boundary conditions. We propose a discretization in space with spectral schemes based on Jacobi polynomials and in time with robust schemes attending to qualitative features such as stiffness and preservation of strong stability for a more correct simulation of non-regular data. Error estimates for the corresponding semidiscrete Galerkin and collocation schemes are derived. The performance of the fully discrete methods is analyzed in a computational study.
