This paper aims to present two nonstandard finite difference (NFSD) methods to solve an
SIR epidemic model. The proposed methods have important properties such as positivity …

In this paper, we present a general form of N th derivative multistep methods. In these hybrid
multistep multiderivative methods, additional stage points (or off-step points) have been …

In this paper, a new family of two-step semi-hybrid schemes of the 12th algebraic order is
proposed for the numerical simulation of initial-value problems of second-order ordinary …

In this paper, we present a new implicit six-step singularly P-stable method with vanished
phase-lag and its derivatives up to fifth order for the numerical integration of the one …

For the perturbed controlled nonlinear delay differential equation with the discontinuous
initial condition, a formula of the analytic representation of solution is proved in the left …

equation with the discontinuous initial condition Skip to content Should you have institutional …

For the perturbed controlled nonlinear delay functional differential equation with the mixed
initial condition a formula of the analytic representation of solution is proved in the left …

The neutral functional-differential equation is a mathematical model of such a system whose
behavior at a given moment depends on the velocity of the system in the past. In the paper …
