On the Existence and Uniqueness of the Weakened Classical Solution on the Axis of the Third Centrally Symmetric Mixed Problem for the Three-Dimensional Nonhomogeneous General Hyperbolic Equation of the Second Order

We demonstrate the existence and uniqueness of the weakened classical solution on the axis of the third centrally symmetric mixed problem for the three-dimensional non-homogeneous general hyperbolic equation of the second order with the minimum conditions on the initial data.
