Elements of Partial Differential Equations by Ian Sneddon: A Review
Partial differential equations (PDEs) are mathematical equations that involve functions of several variables and their partial derivatives. They are widely used to model various phenomena in physics, engineering, and other sciences. However, finding solutions to PDEs can be challenging, especially for students and researchers who are more interested in the applications than the general theory.
That is why Elements of Partial Differential Equations by Ian Sneddon is a valuable resource for anyone who wants to learn the basics of PDEs and how to solve them. The book was first published in 1957 and has been reprinted several times since then. It covers topics such as ordinary differential equations in more than two variables, PDEs of the first and second orders, Laplace's equation, the wave equation, the heat equation, Fourier series, and boundary value problems.
The book is aimed at students of applied rather than pure mathematics, and it assumes some familiarity with calculus and linear algebra. It presents the elements of the theory of PDEs in a form suitable for finding solutions of particular equations rather than developing the general theory. It also provides many examples and exercises to illustrate the methods and concepts.
The book is available as a PDF file for free download from the Internet Archive[^1^]. It has 13 chapters and 224 pages. It is written in a clear and concise style, with a balance between rigor and intuition. It is a classic text that has stood the test of time and remains relevant for anyone who wants to learn more about PDEs.
The book is divided into three parts. The first part deals with ordinary differential equations in more than two variables, and introduces the concepts of linear independence, Wronskian, and linear operators. It also discusses some methods of solving such equations, such as separation of variables, power series, and Frobenius method.
The second part focuses on partial differential equations of the first order, and covers topics such as characteristics, quasi-linear equations, Lagrange's method, Cauchy's problem, and classification of second-order equations. It also explores some applications of first-order PDEs, such as geometrical optics, gas dynamics, and shock waves.
The third part covers partial differential equations of the second order, and presents some classical equations and their solutions, such as Laplace's equation, the wave equation, and the heat equation. It also explains some techniques of solving such equations, such as Fourier series, Fourier transform, Green's functions, and Sturm-Liouville theory. It also examines some boundary value problems and their physical interpretations.
The book is well-organized and easy to follow. It provides clear explanations and derivations of the main results and formulas. It also offers many examples and exercises to help the reader practice and test their understanding. The book is suitable for undergraduate and graduate students who want to learn the basics of PDEs and how to apply them to various problems. 061ffe29dd
