| Abstract: | Based on Lie group method,potential symmetry and invariant solutions for generalized quasilinear hyperbolic equations were studied.To obtain the invariant solutions in explicit form,the physically interesting situations which admit potential symmetries were studied.Then by using the partial Lagrangian approach,the conservation laws for the equation are found in three physically interesting cases. |
