"This book introduces a series of problems and methods insufficiently discussed in the field of Fractional Calculus – a major, emerging tool relevant to all areas of scientific inquiry. The authors present examples based on symbolic computation, written in Maple and Mathematica, and address both mathematical and computational areas in the context of mathematical modeling and the generalization of classical integer-order methods. Distinct from most books, the present volume fills the gap between mathematics and computer fields, and the transition from integer- to fractional-order methods."

"Topics in fractional differential equations is devoted to the existence and uniqueness of solutions for various classes of Darboux problems for hyperbolic differential equations or inclusions involving the Caputo fractional derivative. ​​Fractional calculus generalizes the integrals and derivatives to non-integer orders. During the last decade, fractional calculus was found to play a fundamental role in the modeling of a considerable number of phenomena, in particular the modeling of memory-dependent and complex media such as porous media.

"Persamaan Diferensial-Integral (PDI) dapat memberikan penjelasan untuk berbagai aplikasi dan fenomena dalam fisika. Mencari solusi dari PDI sangat bermanfaat untuk menganalisis dan memahami dinamika permasalahan PDI tersebut. Persamaan Diferensial- Integral Fraksional (PDIF), sebagai perumuman dari PDI, diperoleh melalui penerapan konsep kalkulus fraksional. Saat ini, terdapat banyak model yang semula berorde bilangan bulat positif yang diperumum menjadi orde fraksional. Deret Maclaurin pada kalkulus berorde bilangan bulat positif dapat digunakan sebagai metode untuk menyelesaikan permasalahan PDI. Deret Maclaurin Fraksional (DMF) merupakan perumuman dari deret Maclaurin kalkulus berorde bilangan bulat positif. DMF diterapkan secara konkret dalam menyelesaikan masalah PDIF. Tujuan dari penelitian ini tidak hanya terbatas pada penjelasan konsep DMF, melainkan juga pada penerapannya dalam menangani PDIF. Dengan demikian, pembahasan mencakup gagasangagasan utama, sifat-sifat, dan contoh bagaimana DMF dapat diimplementasikan untuk memberikan solusi pada masalah-masalah PDIF tertentu. Materi untuk menuju pemahaman konsep dan penerapan DMF adalah memahami konsep fungsi gama, fungsi beta, fungsi Mittag-Leffler, integral fraksional dan turunan fraksional. Definisi DMF memuat materi fungsi gama dan turunan-integral fraksional dari fungsi polinomial. Materi-materi yang lain digunakan sebagai pendukung untuk menyelesaikan masalah PDIF. Dengan merinci konsep DMF dan menerapkannya pada penyelesaian PDIF, penelitian ini diharapkan dapat memberikan pemahaman yang lebih dalam terhadap sifat-sifat DMF dan potensinya dalam menangani PDIF. Selain itu, diharapkan hasil penelitian dapat memberikan pandangan yang lebih konkret dan aplikatif melalui contoh-contoh kasus riil pada model-model matematis tertentu.

Differential-Integral Equations (DIEs) can provide explanations for various applications and phenomena in physics. Finding solutions to DIEs is highly beneficial for analyzing and understanding the dynamics of these problems. Fractional Differential-Integral Equations (FDIEs), as a generalization of DIEs, are obtained through the application of fractional calculus concepts. Currently, many models originally based on positive integer orders are generalized to fractional orders. The Maclaurin series in calculus with positive integer orders can be used as a method to solve DIE problems. The Fractional Maclaurin Series (FMS) is a generalization of the Maclaurin series in calculus with positive integer orders. FMS is concretely applied in solving FDIEs problems. The goal of this research is not only limited to explain the concept of FMS but also to its application in handling FDIEs. Therefore, the discussion will cover main ideas, properties, and examples of how FMS can be implemented to provide solutions to specific FDIE problems. The material to understand the concept and application of FMS involves understanding the concepts of gamma function, beta function, Mittag-Leffler function, fractional integral, and fractional derivative. The definition of FMS includes materials on gamma functions and fractional derivative-integral of polynomial functions. Other materials are used as support to solve FDIE problems. By detailing the concept of FMS and applying it to solve FDIEs, this research is expected to provide a deeper understanding of the properties of FMS and its potential in handling FDIEs. Furthermore, it is expected that the research results can provide a more concrete and applicable perspective through real-case examples in specific mathematical models."

"​The Variable-Order Fractional Calculus of Variations is devoted to the study of fractional operators with variable order and, in particular, variational problems involving variable-order operators. This brief presents a new numerical tool for the solution of differential equations involving Caputo derivatives of fractional variable order. Three Caputo-type fractional operators are considered, and for each one, an approximation formula is obtained in terms of standard (integer-order) derivatives only. Estimations for the error of the approximations are also provided.
The contributors consider variational problems that may be subject to one or more constraints, where the functional depends on a combined Caputo derivative of variable fractional order. In particular, they establish necessary optimality conditions of Euler–Lagrange type. As the terminal point in the cost integral is free, as is the terminal state, transversality conditions are also obtained.
The Variable-Order Fractional Calculus of Variations is a valuable source of information for researchers in mathematics, physics, engineering, control and optimization; it provides both analytical and numerical methods to deal with variational problems. It is also of interest to academics and postgraduates in these fields, as it solves multiple variational problems subject to one or more constraints in a single brief."

"This book is designed to serve as a textbook for a course on ordinary differential equations, which is usually a required course in most science and engineering disciplines and follows calculus courses. The book begins with linear algebra, including a number of physical applications, and goes on to discuss first-order differential equations, linear systems of differential equations, higher order differential equations, Laplace transforms, nonlinear systems of differential equations, and numerical methods used in solving differential equations. The style of presentation of the book ensures that the student with a minimum of assistance may apply the theorems and proofs presented. Liberal use of examples and homework problems aids the student in the study of the topics presented and applying them to numerous applications in the real scientific world. This textbook focuses on the actual solution of ordinary differential equations preparing the student to solve ordinary differential equations when exposed to such equations in subsequent courses in engineering or pure science programs. The book can be used as a text in a one-semester core course on differential equations, alternatively it can also be used as a partial or supplementary text in intensive courses that cover multiple topics including differential equations."

"This book offers engineering students an introduction to the theory of partial differential equations and then guiding them through the modern problems in this subject.
Divided into two parts, in the first part readers already well-acquainted with problems from the theory of differential and integral equations gain insights into the classical notions and problems, including differential operators, characteristic surfaces, Levi functions, Green’s function, and Green’s formulas. Readers are also instructed in the extended potential theory in its three forms: the volume potential, the surface single-layer potential and the surface double-layer potential. Furthermore, the book presents the main initial boundary value problems associated with elliptic, parabolic and hyperbolic equations. The second part of the book, which is addressed first and foremost to those who are already acquainted with the notions and the results from the first part, introduces readers to modern aspects of the theory of partial differential equations.
