In this work, a space Hilbert problem is solved, with the boundary condition set on the boundary of the unlimited full bicircular region of class (T∞) or on the boundary of the region Dpq={z∈C2: |z1|p|z2|q<1; p,q∈N}. The main devices used for solving the space Hilbert problem are Temlyakov integrals of second kind.

In this work, the theory of boundary value problems is applied to the problem of decomposition of integral functions of two complex variables of the class [n, σD] into quasi-exponential basises (the received result generalizes the result received by G. D. Derevyanchenko and V. A. Kakichev) as well as to the problem of decomposition of functions, holomorphic in logarithmically convex limited full bicircular regions, into quasi-exponential basises.
