"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.

"For those interested in advanced study and research in nonlinear partial differential equations and nonlinear wave phenomena. Updated modern examples of applications are chosen from areas of fluid dynamics, gas dynamics, plasma physics, nonlinear dynamics, quantum mechanics, nonlinear optics, acoustics, and wave propagation."

"Model pertumbuhan populasi dalam persamaan diferensial parsial (PDP) menggambarkan evolusi jumlah populasi dalam spasial dan waktu. Dalam penerapannya, telah diaplikasikan model PDP dalam ilmu matematika biologi yang disebut Model Diffusive Malthus dan Model Fisher-Kolmogorov.  Pada skripsi ini, model tersebut dikaji kembali dan dimodifikasi menjadi Model Modifikasi Fisher-Kolmogorov, di mana termasuk ke dalam persamaan reaksi-difusi yang dibentuk dari persamaan difusi dan persamaan logistik dengan melibatkan efek perburuan sebagai suku reaksinya. Kedua suku tersebut dan masing-masing parameter di dalamnya memiliki peranan penting karena digunakan untuk mempelajari perilaku solusi, baik secara analitik maupun numerik. Analisis numerik serta simulasinya untuk solusi model ini dikerjakan menggunakan metode beda hingga eksplisit berdasarkan kondisi nilai awal.

Population growth model on partial differential equation (PDE) describes the evolution of the number of population in spatial and time. In this application, there has been applied the PDE model in mathematical biology that is called Diffusive Malthus Model and Fisher-Kolmogorov Model. In this thesis, those model are reviewed and modified becoming Fisher-Kolmogorov Modified Model, where is classified as reaction-diffusion equation which is formed from diffusion equation and logistic equation with involving harvest effect as a reaction term. Both of those terms and each of the parameters on it have important roles that study the solution trajectories, both analytical and numerical. Numerical analysis and its simulation for this model solution are worked using explicit finite difference based on initial conditions."

"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.
