Methods of Theoretical Physics: Part I: Second Edition (Dover Books on Physics)

This second edition updates the classic text for applied mathematics. Its clarity, scope, and content as well as its sheer mathematical elegance make it essential for students of physics or engineering. Part I of the two-volume series covers types of fields, equations governing fields, fields and the variational principle, functions of a complex variable, ordinary differential equations, integral representations, boundary conditions and eigenfunctions, Green's functions, and integral equations. Problem sets and helpful tables conclude each chapter.
