General constraint preconditioning iteration method for singular saddle-point problems
Ai-Li Yang, Guo-Feng Zhang, Yu-Jiang Wu
For the singular saddle-point problems with nonsymmetric positive definite block, we present a general constraint preconditioning (GCP) iteration method based on a singular…

Positivity and Boundedness Preserving Schemes for Space-Time Fractional Predator-Prey Reaction-Diffusion Model
Yanyan Yu, Weihua Deng, Yujiang Wu
The semi-implicit schemes for the nonlinear predator-prey reaction-diffusion model with the space-time fractional derivatives are discussed, where the space fractional derivative i…

Positivity and boundedness preserving schemes for the fractional reaction-diffusion equation
Yanyan Yu, Weihua Deng, Yujiang Wu
In this paper, we design a semi-implicit scheme for the scalar time fractional reaction-diffusion equation. We theoretically prove that the numerical scheme is stable without the r…
