Preface

The investigation of fractional integrals and fractional derivatives has a long history, and they have many real-world applications because of their properties of interpolation between operators of integer order. This field has covered the classical fractional operators such as Riemann–Liouville, Weyl, Caputo, Grunwald–Letnikov, and so on. Also, especially in the last two decades, many new fractional operators have appeared, often defined using integrals with special functions in the kernel as well as their extended or multivariable forms. These have been intensively studied because they can also be useful in modelling and analysing real-world processes, because of their different properties and behaviours, which are comparable to those of the classical operators.

This book contains ten chapters in three sections. The first section, Chaotic Systems and Control, contains three chapters. In Chapter 1, Sene proposed a numerical procedure and its applications to a fractional-order chaotic system represented with the Caputo fractional derivative. In Chapter 2, Okundalaye et al. gave a new multistage optimal homotopy asymptotic method for solutions to a couple of fractional optimal control problems. In Chapter 3, Farman et al. studied a complex chaotic fractional-order financial system in price exponent with control and modelling.

The second part of the book, Heat Conduction, contains two chapters. In Chapter 4, Hristov proposed an attempt to demonstrate that the Duhamel theorem applicable for time-dependent boundary conditions (or time-dependent source terms) of heat conduction in a finite domain and the use of the Fourier method of separation of variable (superposition version) naturally leads to appearance of the Caputo–Fabrizio operators in the solution. In Chapter 5, Avcı and İskender Eroğlu considered the oscillatory heat transfer due to the Cattaneo–Hristov model on the real line modelled by a fractional-order derivative with a non-singular kernel.

The third section of the book, Computational Methods and Their Illustrative Applications, contains five chapters related to different types of real-life problems. In Chapter 6, Ghoreishi et al. applied the optimal homotopy analysis method for a nonlinear fractional-order model to HTLV-1 infection of CD4+ T- cells. In Chapter 7, Durur et al. investigated the behavior analysis and asymptotic stability of the traveling wave solution of the Kaup-Kupershmidt equation with the conformable operator. In Chapter 8, Baishya et al. took into account the Caputo fractional order derivative in the mathematical analysis of a rumor- spreading model and presented interesting numerical results. In Chapter 9, Veeresha et al. studied a unified approach for the fractional system of equations arising in the biochemical reaction without a singular kernel. In Chapter 10, Bora et al. investigated the hydro-morphodynamic effects induced by a non-powered floating object navigating in an approach channel using the CFD (Computational Fluid Dynamics) process.
