Abstract

We consider a boundary value problem with integral nonlocal boundary condition of the first kind for a hyperbolic equation with Bessel differential operator in a rectangular domain. The equivalence of this problem and a local problem with boundary conditions of the second kind is established. The existence and uniqueness of solution of the equivalent problem are proved by means of the spectral method. The solution of the problem is obtained in the form of the Fourier-Bessel series. Convergence is proved in the class of regular solutions.
