B-Splines Based Finite Difference Schemes For Fractional Partial Differential Equations.
PhD thesis, Universiti Sains Malaysia.
Abstract
Fractional partial differential equations (FPDEs) are considered to be the extended
formulation of classical partial differential equations (PDEs). Several physical
models in certain fields of sciences and engineering are more appropriately formulated in the form of FPDEs. FPDEs in general, do not have exact analytical solutions. Thus, the need to develop new numerical methods for the solutions of space and time FPDEs. This research focuses on the development of new numerical methods. Two methods based on B-splines are developed to solve linear and non-linear FPDEs. The methods are extended cubic B-spline approximation (ExCuBS) and new extended cubic B-spline approximation (NExCuBS). Both methods have the same basis functions but for the NExCuBS, a new approximation is used for the second order space derivative.
