The conjugate gradient method for unconstrained optimization problems varies with a scalar. In this note, a general condition conceing the scalar is given, whic
This paper deals with the GPL-stability of the Implicit Runge-Kutta methods for the numerical solutions of the systems of delay differential equations. We focus
In this paper, the theory of parallel multi-stage & multi-step method is discussed, which is a form of combining Runge-Kutta method with linear multi-step metho
We study structure-preserving algorithms to phase space volume for linear dynamical systems y = Ly for which arbitrarily high order explicit symmetric structure
In this paper, a mortar element version for rotated Q1 element is proposed. The optimal error estimate is proven for the rotated Q1 mortar element method.
