Laplace-Type Semi-Invariants for a System of Two Linear Hyperbolic Equations by Complex Methods
In 1773 Laplace obtained two fundamental semi-invariants, called Laplace invariants, for scalar linear hyperbolic partial differential equations (PDEs) in two independent variables. He utilized this in his integration theory for such equations. Recently, Tsaousi and Sophocleous studied semi-invarian...
