- W1996843793 abstract "A complete group classification of a class of variable coefficient (1+1)-dimensional telegraph equations f(x)utt=(H(u)ux)x+K(u)ux, is given, by using a compatibility method and additional equivalence transformations. A number of new interesting nonlinear invariant models which have nontrivial invariance algebras are obtained. Furthermore, the possible additional equivalence transformations between equations from the class under consideration are investigated. Exact solutions of special forms of these equations are also constructed via classical Lie method and generalized conditional transformations. Local conservation laws with characteristics of order 0 of the class under consideration are classified with respect to the group of equivalence transformations." @default.
