We consider a mixed problem with Dirichlet and integral
conditions for a second-order hyperbolic equation with the Bessel
operator. The existence, uniqueness, and continuous dependence of
a strongly generalized solution are proved. The proof is based on
an a priori estimate established in weighted Sobolev spaces and
on the density of the range of the operator corresponding to the
abstract formulation of the considered problem.
