Summary

  This book is a written version of a lecture course that I have conducted over anumber of years at National Tsing Hua University on the subject of mathematical methods for physics In response to student requests, once and again, the main purpose of the book is devoted to motivate students to feel free to study mathematics independently The book is intended to provide advanced undergraduate and beginning graduate students in physical science with the most fundamental tools and important background which they will need in the advanced studies It contains a lot of physical examples appearing in many remarkable reference books, or bursting out
in my research career All examples have been carried out step by step as clear as possible Through the numerous illustrations readers may become familiar with the basic outlook of mathematical methods for physics, recognize the skillful techniques in general, and enable to apply or to extend to advanced problems
