Reaction-diffusion equations arise as mathematical models in a series of important applications. Some difference schemes to the solution of the Fisher's equation are presented.
It is well-known that the environments of most natural populations change with time and that such changes induce variation in the growth characteristics of population which is often modelled by delay differential equations, usually with
time-varying delay. The purpose of this article is to derive a numerical solution
of the delay differential system with continuously distributed delays based on
a composition of -step methods () and quadrature formulas. Some numerical results are presented compared...
Integro-differential equations with time-varying delay can provide us with realistic models of many real world phenomena. Delayed Lotka-Volterra predator-prey systems arise in ecology. We investigate the numerical solution of a system of two integro-differential equations with time-varying delay and the given initial function. We will present an approach based on -step methods using quadrature formulas.
This paper deals with the numerical solution of the Cauchy problem for systems of ordinary differential equations
with time delay. One-step numerical methods and appropriate interpolation operators are used. Numerical results for
a system of three differential equations are presented.
