A new notations -- an reciprocal g-derivative of the 2nd type have been introduced. The problem of interpolation of a functional by an integral continued C-fraction if its value is known on the set of continual nodes has been studied. Expansion functions sin z, cos z, sh x, ch z in functional continued fraction have been got. The boundary-value problem for nonlinear wave equations with a discontinuous right-hand side in an area with a complex edge structure is investigated with the help of constructed structural modification of the two-way method. Sufficient conditions for the existence and uniqueness of the regular and irregular solution of the boundary value problem are established, the theorems on differential inequalities are proved, and the aposteriori estimates of the error of the constructed approximate solution are obtained.
