Multiple-Wave Solutions To Generalized Bilinear Equations In Terms Of Hyperbolic And Trigonometric Solutions

The linear superposition principle is applied to hyperbolic and trigonometric function solutions to generalized bilinear equations. We determine sufficient and necessary conditions for the existence of linear subspaces of hyperbolic and trigonometric function solutions to generalized bilinear equations. By using weights, three examples are given to show applicability of our theory.
