The purpose of this volume is to explore new bridges between different research areas involved in the theory and applications of the fractional calculus. In particular, it collects scientific and original contributions to the development of the theory of nonlocal and fractional operators. Special attention is given to the applications in mathematical physics, as well as in probability. Numerical methods aimed to the solution of problems with fractional differential equations are also treated in the book. The contributions have been presented during the international workshop "Nonlocal and Fractional Operators", held in Sapienza University of Rome, in April 2019, and dedicated to the retirement of Prof. Renato Spigler (University Roma Tre). Therefore we also wish to dedicate this volume to this occasion, in order to celebrate his scientific contributions in the field of numerical analysis and fractional calculus. The book is suitable for mathematicians, physicists andapplied scientists interested in the various aspects of fractional calculus.
"The book provides a survey of recent advancements in nonlocal and fractional models. It covers a vast range of topics involving nonlocal problems, from numerical methods, modeling, and applications to theoretical analysis. ... if you are a researcher working on nonlocal problems, or if you are a mathematician or applied scientist who is interested in learning the state-of-the-art theoretical and numerical developments in this field, this book will make a nice addition to your library."
