This book provides efficient and reliable numerical methods for solving fractional calculus problems. It focuses on numerical techniques for fractional integrals, derivatives, and …
Fractional calculus, which has two main features—singularity and nonlocality from its origin— means integration and differentiation of any positive real order or even complex order. It has …
Fractional calculus, albeit a synonym of fractional integrals and derivatives which have two main characteristics—singularity and nonlocality—has attracted increasing interest due to its …
This paper investigates chaotic behavior and stability of fractional differential equations within a new generalized Caputo derivative. A semi–analytical method is proposed based …

The fractional Fokker--Planck equation is an important physical model for simulating anomalous diffusions with external forces. Because of the nonlocal property of the fractional …
For the first time in literature, semi-implicit spectral approximations for nonlinear Caputo time- and Riesz space-fractional diffusion equations with both smooth and non-smooth solutions …
