On straightening the characteristics of a quasilinear second-order equation
F. Kh. Mukminov
Abstract:
An invertible transformation that preserves the class of quasilinear
second-order equations is proposed. Necessary and sufficient
conditions are found under which this transformation carries a quasilinear
equation into an equation with straight characteristics. For
one quasilinear equation the general solution is found by means of
the transformation. Examples of Lagrangians of the form $L(u,u_xu_y)$ possessing conservation laws of high order are given.
