Abstract
We study a mixed problem with purely integral conditions for a
class of two-dimensional second-order hyperbolic equations. We
prove the existence, uniqueness, and the continuous dependence
upon the data of a generalized solution. We use a functional
analysis method based on a priori estimate and on the density of
the range of the operator generated by the considered
problem.
