On nonstandard finite difference schemes in biosciences [PDF]
AIP Conference Proceedings, 2012 We design, analyze and implement nonstandard finite difference (NSFD) schemes for some differential models in biosciences. The NSFD schemes are reliable in three directions. They are topologically dynamically consistent for onedimensional models. They can replicate the global asymptotic stability of the disease-free equilibrium of the MSEIR model in ...

Non standard finite difference scheme preserving dynamical properties [PDF]
Journal of Computational and Applied Mathematics, 2014 We study the construction of a non-standard finite differences numerical scheme for a general class of two dimensional differential equations including several models in population dynamics using the idea of non-local approximation introduced by R ...

On Pairs of Difference Operators Satisfying: [P,Q] = Id
, 1997 Different finite difference replacements for the derivative are analyzed in the context of the Heisenberg commutation relation. The type of the finite difference operator is shown to be tied to whether one can naturally consider $P$ and $X$ to be self ...

Solving space-fractional Cauchy problem by modified finite-difference discretization scheme
Alexandria Engineering Journal, 2020 This paper deals with the stability convergence analysis for SFCE in the sense of Riemann-Liouville derivative. A modified FDDS is developed utilizing the fractionally-shifted Grünwald formula in handling the SFCE.

Invariant compact finite difference schemes
, 2019 In this paper, we propose a method, that is based on equivariant moving frames, for development of high order accurate invariant compact finite difference schemes that preserve Lie symmetries of underlying partial differential equations. In this method, variable transformations that are obtained from the extended symmetry groups of PDEs are used to ...
