A Class of Multiderivative Hybrid One-step Methods
hybrid one-step method rational approximation
2007/12/11
This paper presents a class of hybrid one-step methods that are obtained by using Cramer's rule and rational approximation to function exp(q). The algorithms fall into the catalogue of implicit formul...
In this paper, a new step-size skill for a projection and contraction
method$^{[10]}$ for linear programming is generalized to an iterative
method$^{[22]}$ for solving nonlinear projection equation....

A Note on Symplecticity of Step-Transition Mappings for Multi-Step Methods
Linear multi-step method Infinitesimally symplectic Symplecticity General linear method

We prove that for a linear multi-step methodm
k=0kZk =m
k=0kf (Zk), even though the mappings Z0 → Z1, . . . , Zm−2 →
Zm−1 are chosen to be symplectic, Zm−1 → Zm will be non-s...
Expansions of Step-transition Operators of Multi-step Methods and Order Barriers for Dahlquist Pairs
Linear Multi-Step Method Step-Transition Operator B-series Dahlquist (Conjugate) Relation Symplecticity
2012/7/31
Using least parameters, we expand the step-transition operator of any linear multistep method (LMSM) up to O(?s+5) with order s = 1 and rewrite the expansion of the step-transition operator for s = 2 ...
