Book Summary

The subject of this book is the fractional calculus which treats differentiation and integration to fractional order. This book presents a new approach to the fractional calculus being based on linear differentiator-like operators to arbitrary order. In this book, many theorems, corollaries, and lemmas are derived to reveal the properties of fractional differentiation and integration. Various special functions of arbitrary order are derived from this theory. Applications are also given to the solutions of basic differintegral equations, diffusion equations, Schroedinger's equations, electric circuits, and electromagnetic wave propagation problems.

From the Author

In this book, a differentiation operator in fractional calculus is generalized to a more general operator that I call semi p-operator which may be linear or nonlinear. Then, we consider a function sequence called the lambda-sequence generated by an operator-based equation p^n f = lambda_n f. From the generating function of the lambda-sequence, its integral representation in a complex region is derived. Like the Gamma function which is an extension of a factorial, we can extend an index n of the lambda_n to an arbitrary complex value z via its integral representation. Thereby we can define a linear semi p-operator to arbitrary order. The classical fractional calculus can be derived as a special case. Various special functions of arbitrary order follow from lambda_z by choosing different pairs of p and f. Applications of the theory are given in the last chapter with special emphasis on electromagnetic wave problems. The author believes that the presented theory will provide fractional calculus and special function theory with a new approach.
