<p><i>Linear Partial Differential and Difference Equations and Simultaneous Systems: With Constant or Homogeneous Coefficients </i>is part of the series "Mathematics and Physics for Science and Technology", which combines rigorous mathematics with general physical principles to model practical engineering systems with a detailed derivation and interpretation of results. Volume V presents the mathematical theory of partial differential equations and methods of solution satisfying initial and boundary conditions, and includes applications to: acoustic, elastic, water, electromagnetic and other waves; the diffusion of heat, mass, and electricity; and their interactions. This is the third book of the volume.</p><p>The book starts with six different methods of solution of linear partial differential equations (P.D.E.s) with constant coefficients. One of the methods, namely characteristic polynomial, is then extended to a further five classes, including linear P.D.E.s with homogeneous powe
