A Residual-Certified Product-Integration Method for Nonlinear Caputo–Volterra Equations

open access: yes
We study an implicit product-integration scheme for nonlinear Caputo initial-value problems written as weakly singular Volterra equations. The Abel kernel is integrated exactly against a piecewise-linear interpolant of the nonlinear term, producing a ...

An Algorithm For The Numerical Solution Of Differential Equations Of Fractional Order

open access: yes, 1997
. Differential equations involving derivatives of non-integer order have shown to be adequate models for various physical phenomena in areas like damping laws, diffusion processes, etc.

Exponential Integrators For Quantum-Classical Molecular Dynamics

open access: yes, 1999
. We study time integration methods for equations of mixed quantum-classical molecular dynamics in which Newtonian equations of motion and Schrodinger equations are nonlinearly coupled. Such systems exhibit different time scales in the classical and the

On Taylor model based integration of ODEs

open access: yes, 2008
. Interval methods for verified integration of initial value problems (IVPs) for ODEs have been used for more than 40 years. For many classes of IVPs, these methods are able to compute guaranteed error bounds for the flow of an ODE, where traditional ...
