Mathematical physics method is an important basic course for physics department and some engineering undergraduates. It is another important basic mathematics course on the basis of advanced mathematics course, which will provide basic mathematical processing tools for learning physics courses. The contents of the book are divided into 10 chapters, which introduce the basic knowledge of vector analysis and field theory, the derivation of definite solutions of mathematical physics, the separation of variables, traveling wave method and integral transformation method, Green's function method, variational method, series solutions of second-order linear ordinary differential equations and Sturm? Basic knowledge of Joseph Liouville eigenvalue problem, special function (1)- legendre polynomials, special function (2)- Bessel function and integral equation. This book takes into account the characteristics of electronics and communication specialty from theory to examples, taking into account the rigor of mathematical theory and the distinctiveness of physical background, and embodies the role of mathematical physics methods as a bridge between mathematics, physics and other sciences. This book can be used as a teaching material for engineering graduate students in colleges and universities.
