Higher order compact finite difference method for the solution of 2-D time fractional diffusion equation [PDF]
The main purpose of this study is to work on the solution of two-dimensional time fractional diffusion equation In this research work we apply the HOC scheme to approximate the second order space derivative. To obtain a discrete implicit scheme, Grunwald-

Solution of the Porous Media Equation by a Compact Finite Difference Method [PDF]
Accurate solutions of the porous media equation that usually occurs in nonlinear problems of heat and mass transfer and in biological systems are obtained using a compact finite difference method in space and a low‐storage total variation diminishing third‐order Runge‐Kutta scheme in time.

An Efficient Compact Finite Difference Method for the Solution of the Gross-Pitaevskii Equation
We present an efficient, unconditionally stable, and accurate numerical method for the solution of the Gross-Pitaevskii equation. We begin with an introduction on the gradient flow with discrete normalization (GFDN) for computing stationary states of a ...

A Compact Scheme for a Partial Integro-Differential Equation with Weakly Singular Kernel [PDF]
Compact finite difference scheme is applied for a partial integro-differential equation with a weakly singular kernel. The product trapezoidal method is applied for discretization of the integral term. The order of accuracy in space and time is , where .
