On an inverse problem for a system of quazilinear equations in partial derivatives of the first order

A method of studying solubility of an inverse problem for the system of quasilinear differential equations in partial derivatives of the first order is offered. With the help of a nonlinear method of characteristics based on introduction of an additional parameter, a Cauchy problem is reduced to study the system of non-linear integral equations. For solution the inverse problem the restored functions are found from the system of Volterra non-linear integral equations of the first kind with the help of nonlinear integral transformation.
