An Introduction to Phase-Integral Methods Ideal for the novice orThe phase integral method in mathematics, also known as the Wentzel Kramers Brillouin (WKB) method, is the focus of this introductory treatment. Author John Heading successfully steers a course between simplistic and rigorous approaches to provide a concise overview for advanced undergraduates and graduate students in mathematics and physics. Since the number of applications is vast, the text considers only a brief selection of topics and emphasizes
