Computer Methods for Ordinary Differential Equations and Differential-Algebraic Equations
Uri M. Ascher,Linda R. Petzold +1 more
TL;DR: This book is a practical and mathematically well informed introduction that emphasizes basic methods and theory, issues in the use and development of mathematical software, and examples from scientific engineering applications.
Numerical solution of boundary value problems for ordinary differential equations
TL;DR: In this article, the Riccati method is used to solve boundary value problems for Ordinary Differential Equations and to solve nonlinear problems for BVPSs in the standard form.
Journal ArticleDOI
Implicit-explicit Runge-Kutta methods for time-dependent partial differential equations
TL;DR: Runge-Kutta-based IMEX schemes are developed that have better stability regions than the best known IMEX multistep schemes over a wide parameter range.

TL;DR: This book discusses Consistency, Stability, and Convergence higher-Order One-Step Schemes Collocation Theory Acceleration Techniques Higher-Order ODEs Finite Element Methods and Initial Value Methods.
Journal ArticleDOI
Implicit-explicit methods for time-dependent partial differential equations
TL;DR: This work systematically analyze the performance of implicit-explicit IMEX schemes, propose improved new schemes, and pay particular attention to their relative performance in the context of fast multigrid algorithms and of aliasing reduction for spectral methods.
