On the One-Leg Methods for Solving Nonlinear Neutral Differential Equations with Variable Delay

Stability of two classes of improved backward Euler methods for stochastic delay differential equations of neutral type

This paper examines stability analysis of two classes of improved backward Euler methods, namely split-step $(theta, lambda)$-backward Euler (SSBE) and semi-implicit $(theta,lambda)$-Euler (SIE) methods, for nonlinear neutral stochastic delay differential equations (NSDDEs). It is proved that the SSBE method with $theta, lambdain(0,1]$ can recover the exponential mean-square stability with some...

Differential transformation method for solving a neutral functional-differential equation with proportional delays

In this article differential transformation method (DTMs) has been used to solve neutral functional-differential equations with proportional delays. The method can simply be applied to many linear and nonlinear problems and is capable of reducing the size of computational work while still providing the series solution with fast convergence rate. Exact solutions can also be obtained from the kno...

Dissipativity of θ-methods and one-leg methods for nonlinear neutral delay integro-differential equations

In this paper we study the dissipativity of a special class of nonlinear neutral delay integro-differential equations. The dissipativity of three kinds of important numerical methods, the linear θ-methods, one-leg θmethods, and the one-leg methods is obtained when they are applied to these problems. Numerical experiments are presented to check our findings. Key–Words: Linear θ-methods, One-leg ...
