Preliminary group classification of the general quasi-linear wave equation
We begin the group classification of quasi-linear second-order wave equations of the most general form. We find the canonical forms for the symmetry operators which generate the invariance group of the equation, as well as the equivalence group, and we describe those equations which admit one- and t...

Transactions of Institute of Mathematics of NAS of Ukraine| Резюме: | We begin the group classification of quasi-linear second-order wave equations of the most general form. We find the canonical forms for the symmetry operators which generate the invariance group of the equation, as well as the equivalence group, and we describe those equations which admit one- and two-dimensional invariance groups. |
