Linear multistep methods for optimal control problems and applications to hyperbolic relaxation systems [PDF]

open access: yes, 2018
We are interested in high-order linear multistep schemes for time discretization of adjoint equations arising within optimal control problems. First we consider optimal control problems for ordinary differential equations and show loss of accuracy for ...

Stability of one-step and linear multistep methods - a matrix technique approach

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2016
We investigate the stability of one-step and linear multistep methods from a new direction. Our aim is to modify the long and technical proof which is consequently omitted in almost every textbook and make it user-friendly.

Exponential Multistep Methods for Stiff Delay Differential Equations

open access: yesAxioms, 2022
Stiff delay differential equations are frequently utilized in practice, but their numerical simulations are difficult due to the complicated interaction between the stiff and delay terms.

Linear multistep methods and global Richardson extrapolation

open access: yesApplied Mathematics Letters, 2022
In this work, we study the application the classical Richardson extrapolation (RE) technique to accelerate the convergence of sequences resulting from linear multistep methods (LMMs) for solving initial-value problems of systems of ordinary differential equations numerically.

On overcoming Dahlquist’s second barrier for$A$-stable linear multistep methods [PDF]

open access: yesIranian Journal of Numerical Analysis and Optimization
Dahlquist’s second barrier limits the order of $A$-stable linear multistep methods to at most two, posing significant challenges for achieving higher accuracy in the numerical solution of stiff ordinary differential equations.

Estimation of Longest Stability Interval for a Kind of Explicit Linear Multistep Methods

open access: yesDiscrete Dynamics in Nature and Society, 2010
The new explicit linear three-order four-step methods with longest interval of absolute stability are proposed. Some numerical experiments are made for comparing different kinds of linear multistep methods.

Multigrid Waveform Relaxation on Spatial Finite Element Meshes: The Discrete-Time Case [PDF]

open access: yes, 1996
The efficiency of numerically solving time-dependent partial differential equations on parallel computers can be greatly improved by computing the solution on many time levels simultaneously.

Full linear multistep methods as root-finders [PDF]

open access: yesApplied Mathematics and Computation, 2018
Root-finders based on full linear multistep methods (LMMs) use previous function values, derivatives and root estimates to iteratively find a root of a nonlinear function. As ODE solvers, full LMMs are typically not zero-stable. However, used as root-finders, the interpolation points are convergent so that such stability issues are circumvented.

On monotonicity and boundedness properties of linear multistep methods [PDF]

open access: yesMathematics of Computation, 2005
In this paper an analysis is provided of nonlinear monotonicity and boundedness properties for linear multistep methods. Instead of strict monotonicity for arbitrary starting values we shall focus on generalized monotonicity or boundedness with Runge-Kutta starting procedures.
