Dirichlet Problem in Parallelepiped for Elliptic Equation with Three Singular Coefficients

We study the Dirichlet problem in the parallelepiped for an equation that is an analogue of the generalized bi-axisymmetric Helmholtz equation for the case of three independent variables. Using spectral analysis methods, we prove the uniqueness of the solution to the problem under study. The solution is constructed in the form of a double series using expansion in a Fourier-Bessel series. Sufficient conditions for the initial data of the problem are found under which the corresponding series converge uniformly and a solution exists.
