About this book :-
"Ordinary Differential Equations: An Elementary Text-Book, with an Introduction to Lie’s Theory of the Group of One Parameter" by "James Morris Page" is a well-structured introductory book aimed at students learning the fundamentals of ordinary differential equations. It explains standard solution methods for first- and higher-order equations in a clear and systematic way, making it suitable for undergraduate mathematics, physics, and engineering students. The presentation emphasizes understanding techniques through carefully explained examples rather than heavy abstraction. A notable strength of the book is its inclusion of "Lie’s theory of one-parameter groups" at an elementary level. Page shows how symmetry methods can be used to reduce and solve "ordinary differential equations", helping readers see connections between classical solution techniques and more advanced mathematical ideas. This approach provides historical and theoretical context while remaining accessible to beginners. Because of its balanced treatment of theory and application, the book serves both as a primary learning text and as a bridge to more advanced studies in "differential equations" and "applied mathematics". Even today, it remains valuable for readers interested in classical methods, symmetry analysis, and the early development of Lie theory in differential equations.
