An isotropy-improved nonstandard finite-difference time-domain method

IEEE Transactions on Antennas and Propagation, 2006
By introducing extra degree of freedom into the space- domain stencils, an isotropy-improved nonstandard finite-differ- ence (NSFD) (2,2) method is presented in this paper. The technique is also extended to the higher-order (2,4) stencils. Both analytical and numerical results are presented and compared to demonstrate the accuracy and the strengths of ...

Exact nonstandard finite-difference methods for a linear system – the case of centers

Journal of Difference Equations and Applications, 2008
A system of two linear differential equations with constant coefficients is considered, where and a 2+bc ≠ 0. Let , if a 2+bc>0, and , if ; then the two eigenvalues of A have opposite signs, ± α or ± iβ. When the two eigenvalues are ± iβ, the linear system has a center at (0,0). For this system, there exists a simple exact nonstandard finite-difference

An unconditionally stable nonstandard finite difference method to solve a mathematical model describing Visceral Leishmaniasis

Mathematics and Computers in Simulation, 2021
In this paper, a mathematical model of Visceral Leishmaniasis is considered. The model incorporates three populations, the human, the reservoir and the vector host populations. A detailed analysis of the model is presented. This analysis reveals that the

Nonstandard finite difference method by nonlocal approximation

Mathematics and Computers in Simulation, 2003
Two types of monotonic properties of solutions of differential equations are discussed and general finite difference schemes, which are stable with respect to these properties are investigated. Apart from being elementary stable, these schemes are also shown to preserve qualitative properties of nonhyperbolic fixed points of the differential equations.
