Overimplicit multistep methods [PDF]

open access: yesApplications of Mathematics, 1973
The paper is concerned with the numerical solution of ordinary differential equations by a new class of methods called overimplicit multistep methods. The effort is devoted to the study of the convergence and $A$-stability of the introduced methods. $A$-stable formulae of arbitrarily high orders are shown to exist in this new class.

Grid-Independent Construction of Multistep Methods [PDF]

open access: yesJournal of Computational Mathematics, 2018
A new polynomial formulation of variable step size linear multistep methods is presented, where each k-step method is characterized by a fixed set of $k-1$ or $k$ parameters. This construction includes all methods of maximal order ($p=k$ for stiff, and $p=k+1$ for nonstiff problems).

Finite element multistep multideriavative schemes for parabolic equations [PDF]

open access: yes, 1976
The linear, homogeneous, parabolic equation is solved by applying finite element discretizations in space and A0 —stable, linear multistep, multiderivative (L.M.S.D.) methods in time. Such schemes are unconditionally stable. An error analysis establishes

Theoretical results of one class of multiderivative methods through order stars [PDF]

open access: yes, 2011
Order stars are applied to Brown (K,L) methods. They are displayed pictorially for a selection of methods and are used to provide succinct proofs of existing results.

Extended Convergence of Two Multi-Step Iterative Methods

open access: yesFoundations, 2023
Iterative methods which have high convergence order are crucial in computational mathematics since the iterates produce sequences converging to the root of a non-linear equation. A plethora of applications in chemistry and physics require the solution of

Probabilistic Linear Multistep Methods [PDF]

open access: yesCoRR, 2016
We present a derivation and theoretical investigation of the Adams-Bashforth and Adams-Moulton family of linear multistep methods for solving ordinary differential equations, starting from a Gaussian process (GP) framework. In the limit, this formulation coincides with the classical deterministic methods, which have been used as higher-order initial ...

Generalized Implicit-Update in Multi-Step QN Methods [PDF]

open access: yesالمجلة العراقية للعلوم الاحصائية, 2007
In this paper, we have generalized the implicit update of the Quasi-Newton’s condition. We have here investigated a four; five and n-step update algorithm. We have applied the cases at four and five- step numerically and we have compared these cases with

A Family of Multi-Step Subgradient Minimization Methods

open access: yesMathematics, 2023
For solving non-smooth multidimensional optimization problems, we present a family of relaxation subgradient methods (RSMs) with a built-in algorithm for finding the descent direction that forms an acute angle with all subgradients in the neighborhood of

Interval versions for special kinds of explicit linear multistep methods

open access: yesResults in Applied Mathematics, 2020
In classical theory of explicit linear multistep methods there are known special kinds of methods which have less function evaluations (in comparison to other multistep methods) and, nevertheless, they give the same accuracy (order) of the approximations
