First-Order Partial Differential Equations, Vol. 1 This volume is a well-knownThis first volume of a highly regarded two volume text is fully usable on its own. After going over some of the preliminaries, the authors discuss mathematical models that yield first order partial differential equations; motivations, classifications, and some methods of solution; linear and semilinear equations; chromatographic equations with finite rate expressions; homogeneous and nonhomogeneous quasilinear equations; formation and propagation of
