数学物理方法II

This book systematically provides necessary basic mathematical methods for solving all kinds of important physical problems. This book was published in three volumes, the content of volume II has nothing to do with volume I, to deal with the theory of partial differential equations from the view of mathematical physics, including: general theory of first-order partial differential equations, partial differential equation of higher order, potential theory and elliptic differential equation, two independent variable hyperbolic differential equations and more than two independent variable hyperbolic differential equations.
