Nonresonance case for differential equations with degeneration

We study what form the asymptotics of solutions of degenerate elliptic equations have in the nonresonance case under the condition that the asymptotics of the right-hand side have the form corresponding to the class of asymptotics of the nonresonance case, that is, the case in which the singularities of the right-hand side do not coincide with the zeros of the left-hand side. We show that, in the resonance case, the problem is no longer closed in this class.
