Second-order and nonuniform time-stepping schemes for time fractional evolution equations with time-space dependent coefficients
Pin Lyu, Seakweng Vong
The numerical analysis of time fractional evolution equations with the second-order elliptic operator including general time-space dependent variable coefficients is challenging, e…
A symmetric fractional-order reduction method for direct nonuniform approximations of semilinear diffusion-wave equations
Pin Lyu, Seakweng Vong
We introduce a symmetric fractional-order reduction (SFOR) method to construct numerical algorithms on general nonuniform temporal meshes for semilinear fractional diffusion-wave e…
An efficient second-order convergent scheme for one-side space fractional diffusion equations with variable coefficients
Xue-lei Lin, Pin Lyu, Michael K. Ng +2
In this paper, a second order finite difference scheme is investigated for time-dependent one-side space fractional diffusion equations with variable coefficients. The existing sch…
A linearized second-order scheme for nonlinear time fractional Klein-Gordon type equations
Pin Lyu, Seakweng Vong
We consider difference schemes for nonlinear time fractional Klein-Gordon type equations in this paper. A linearized scheme is proposed to solve the problem. As a result, iterative…
On a second order scheme for space fractional diffusion equations with variable coefficients
Seakweng Vong, Pin Lyu
We study a second order scheme for spatial fractional differential equations with variable coefficients. Previous results mainly concentrate on equations with diffusion coefficient…
