Introduction:

This book is the research result of the Ministry of Education's "Reform Plan of Teaching Content and Curriculum System of Higher Education Facing 2 1 century", and it is a curriculum textbook facing 2 1 century and a national planning textbook for general higher education during the Tenth Five-Year Plan period.

This book systematically expounds the basic theory of mathematical physics method and its application in physics and engineering technology. The key point is not to blindly pursue the rigor and logic of mathematics, that is, the integrity of pure mathematical theory, but to strive to provide readers with basic concepts, basic theorems and various methods and skills related to mathematical physics methods. Although this book involves some traditional contents, it is stronger in depth and breadth than the previous textbooks; At the same time, the book also adds a lot of contents that reflect the frontier of the discipline, so that students can not only acquire systematic scientific knowledge of related disciplines, but also guide students to enter the frontier of contemporary science. In addition, another feature of this book is that readers can not only obtain simplified and unified basic knowledge of mathematics from the logical structure of this book, but also see unique, concise and practical solutions from the examples in the book.

This book can be used as an undergraduate teaching material for non-mathematics majors of science and engineering in colleges and universities, and can also be used as a reference for graduate students, teachers and scientific and technological personnel of related majors.
