"This text provides an accessible, self-contained and rigorous introduction to complex analysis and differential equations. Topics covered include holomorphic functions, Fourier series, ordinary and partial differential equations. The text is divided into two parts, part one focuses on complex analysis and part two on differential equations. Each part can be read independently, so in essence this text offers two books in one. In the second part of the book, some emphasis is given to the application of complex analysis to differential equations. Half of the book consists of approximately 200 worked out problems, carefully prepared for each part of theory, plus 200 exercises of variable levels of difficulty."

"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."

"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.
