We study a model case where the unit disk is chosen as a domain and the equation does not contain lowest terms. We prove that the problem has a unique solution in the Sobolev space for special classes of Dirichlet data that are spaces of functions with exponential decrease of the Fourier coefficients.}, number={2}, journal={Ukrainsâ€™kyi Matematychnyi Zhurnal}, author={BurskiiV.
