Analysis, Probability And Mathematical Physics On Fractals
In the 50 years since Mandelbrot identified the fractality of coastlines, mathematicians and physicists have developed a rich and beautiful theory describing the interplay between analytic, geometric and probabilistic aspects of the mathematics of fractals. Using classical and abstract analytic tools developed by Cantor, Hausdorff, and Sierpinski, they have sought to address fundamental questions: How can we measure the size of a fractal set? How do waves and heat travel on irregular structures? How are analysis, geometry and stochastic processes related in the absence of Euclidean smooth structure? What new physical phenomena arise in the fractal-like settings that are ubiquitous in nature?This book introduces background and recent progress on these problems, from both established leaders in the field and early career researchers. The book gives a broad introduction to several foundational techniques in fractal mathematics, while also introducing some specific new and significant results of interest to experts, such as that waves have infinite propagation speed on fractals. It contains sufficient introductory material that it can be read by new researchers or researchers from other areas who want to learn about fractal methods and results.

Introduzione ai frattali in fisica
La geometria frattale permette di caratterizzare le strutture complesse e irregolari che godono della proprietà di invarianza di scala. Introdotta da Mandelbrot nel 1975, spiega in modo convincente che la natura ci pone di fronte a molti esempi di strutture complesse che godono di proprietà peculiari: è un fatto che in natura l’irregolarità sia molto comune, come dimostrano le strutture di piante, montagne, nuvole e fulmini. La nuova geometria introduce concetti che facilitano la descrizione di un gran numero di fenomeni naturali e sociali. In moltissimi casi di tipo tradizionale l’uso dei calcolatori ha permesso di ottenere soluzioni accurate di problemi complicati; nel caso delle strutture frattali, il loro ruolo è stato ancor più fondamentale: i modelli matematici in questo campo sono di carattere iterativo e quindi particolarmente adatti a essere programmati.Il volume nasce dall’esperienza didattica sviluppata dall’autore in oltre un decennio di insegnamento di Istituzioni di Fisica Superiore presso l’Università di Pavia e intende colmare la lacuna nel panorama italiano di testi didattici su tematiche frattali. Parte dalla definizione di oggetti e di funzioni frattali, introducendo la dimensione “non intera” e la “codimensione” di un insieme, di una figura geometrica e la sua estensione a una funzione matematica irregolare. Segue l’introduzione dei frattali stocastici (fino ai frattali universali) che tengono nel dovuto conto la natura parzialmente caotica dei fenomeni fisici. Di particolare rilevanza un capitolo che compendia la trattazione di fenomeni caotici e introduce gli attrattori strani di Edward Lorenz. Infine il volume affronta l’applicazione dei concetti frattali alla fisica cosmica, all’econofisica e alla descrizione dell’inquinamento prodotto da due disastri ambientali: l’incidente chimico di Seveso e quello nucleare di Chernobyl.Il testo si rivolge in primo luogo agli studenti dei corsi di Laurea Magistrale in Fisica, Chimica, Ingegneria e Scienze Ambientali; può costituire comunque un valido ausilio come testo complementare di natura applicativa. Il carattere propedeutico del volume si presta agevolmente a un apprendimento autonomo individuale.

Fractals in Engineering: Theoretical Aspects and Numerical Approximations
Fractal structures or geometries currently play a key role in all models for natural and industrial processes that exhibit the formation of rough surfaces and interfaces. Computer simulations, analytical theories and experiments have led to significant advances in modeling these phenomena across wild media. Many problems coming from engineering, physics or biology are characterized by both the presence of different temporal and spatial scales and the presence of contacts among different components through (irregular) interfaces that often connect media with different characteristics. This work is devoted to collecting new results on fractal applications in engineering from both theoretical and numerical perspectives. The book is addressed to researchers in the field.

Fractional Calculus with Applications in Mechanics
The books Fractional Calculus with Applications in Mechanics: Vibrations and Diffusion Processes and Fractional Calculus with Applications in Mechanics: Wave Propagation, Impact and Variational Principles contain various applications of fractional calculus to the fields of classical mechanics. Namely, the books study problems in fields such as viscoelasticity of fractional order, lateral vibrations of a rod of fractional order type, lateral vibrations of a rod positioned on fractional order viscoelastic foundations, diffusion-wave phenomena, heat conduction, wave propagation, forced oscillations of a body attached to a rod, impact and variational principles of a Hamiltonian type. The books will be useful for graduate students in mechanics and applied mathematics, as well as for researchers in these fields. Part 1 of this book presents an introduction to fractional calculus. Chapter 1 briefly gives definitions and notions that are needed later in the book and Chapter 2 presents definitions and some of the properties of fractional integrals and derivatives. Part 2 is the central part of the book. Chapter 3 presents the analysis of waves in fractional viscoelastic materials in infinite and finite spatial domains. In Chapter 4, the problem of oscillations of a translatory moving rigid body, attached to a heavy, or light viscoelastic rod of fractional order type, is studied in detail. In Chapter 5, the authors analyze a specific engineering problem of the impact of a viscoelastic rod against a rigid wall. Finally, in Chapter 6, some results for the optimization of a functional containing fractional derivatives of constant and variable order are presented.

Unification of Fractional Calculi with Applications
This book demonstrates the unifying methods of generalized versions of Hilfer, Prabhakar and Hilfer–Prabhakar fractional calculi, and we establish related unifying fractional integral inequalities of the following types: Iyengar, Landau, Polya, Ostrowski, Hilbert–Pachpatte, Hardy, Opial, Csiszar’s f-Divergence, self-adjoint operator and related to fuzziness. Our results are univariate and multivariate. This book’s results are expected to find applications in many areas of pure and applied mathematics, especially in fractional inequalities and fractional differential equations. Other interesting applications can be in applied sciences like geophysics, physics, chemistry, economics and engineering. This book is appropriate for researchers, graduate students, practitioners and seminars of the above disciplines, also to be in all science and engineering libraries.

Fractional-in-Time Semilinear Parabolic Equations and Applications
This book provides a unified analysis and scheme for the existence and uniqueness of strong and mild solutions to certain fractional kinetic equations. This class of equations is characterized by the presence of a nonlinear time-dependent source, generally of arbitrary growth in the unknown function, a time derivative in the sense of Caputo and the presence of a large class of diffusion operators. The global regularity problem is then treated separately and the analysis is extended to some systems of fractional kinetic equations, including prey-predator models of Volterra–Lotka type and chemical reactions models, all of them possibly containing some fractional kinetics.Besides classical examples involving the Laplace operator, subject to standard (namely, Dirichlet, Neumann, Robin, dynamic/Wentzell and Steklov) boundary conditions, the framework also includes non-standard diffusion operators of "fractional" type, subject to appropriate boundary conditions.This book is aimed at graduate students and researchers in mathematics, physics, mathematical engineering and mathematical biology, whose research involves partial differential equations.

Fractional Dispersive Models and Applications
This book explores the role of fractional calculus and associated partial differential equations in modeling multiscale phenomena and overlapping macroscopic & microscopic scales, offering an innovative and powerful tool for modeling complex systems. While integer order PDEs have a long-standing history, the novel setting of fractional PDEs opens up new possibilities for the simulation of multi-physics phenomena. The book examines a range of releavant examples that showcase the seamless transition from wave propagation to diffusion or from local to non-local dynamics in both continuum and discrete systems. These systems have been argued as being particularly relevant in contexts such as nonlinear optics, lattice nonlinear dynamical systems, and dispersive nonlinear wave phenomena, where the exploration of the potential fractionality has emerged as a highly active topic for current studies.The volume consists of contributions from a diverse group of active scholars and experts across different fields, providing a detailed examination of the field's past, present, and future state-of-the-art in the interplay of fractional PDEs and nonlinear wave phenomena. It is intended to be of wide interest to both seasoned researchers and beginners in the Field of Nonlinear Science. This book sets the stage for the next decade of research and beyond and is a timely and relevant reference of choice for this crucial junction of current research.
