We study the inverse problem related to finding the unknown right-hand side of the equation of mixed parabolic-hyperbolic type in a rectangular domain. A uniqueness criterion for the solution is established. The solution is constructed as the sum of the series in eigenfunctions of the corresponding one-dimensional spectral problem.
Keywords: equation of mixed parabolic-hyperbolic type, spectral problem, irrational algebraic number
Mots-clés : Weierstrass test for uniform convergence.
