Strong convergence rates for backward Euler–Maruyama method for non-linear dissipative-type stochastic differential equations with super-linear diffusion coefficients [PDF]

open access: yes, 2012
In this work, we generalize the current theory of strong convergence rates for the backward Euler–Maruyama scheme for highly non-linear stochastic differential equations, which appear in both mathematical finance and bio-mathematics.

The use of mathematical programming to control inbreeding in selection schemes [PDF]

open access: yesJournal of Animal Breeding and Genetics, 1999
IntroductionSelection on the best estimate of the breeding value of individuals should, in large populations, provide the maximal response in breeding value. However, many breeders deal with the selection of small numbers of animals from relatively small populations and therefore there is a trend for inbreeding to rise because of genetic drift ...

Numerical Schemes for Fractional Energy Balance Model of Climate Change with Diffusion Effects

open access: yesEmerging Science Journal, 2023
This study aims to propose numerical schemes for fractional time discretization of partial differential equations (PDEs). The scheme is comprised of two stages. Using von Neumann stability analysis, we ensure the robustness of the scheme.
