We consider conditions under which the second order elliptic equation has no positive solutions defined in the semiinfinite cylinder. The conditions of the absence of solutions are established in terms of degeneration of positive low coefficient.
Mots-clés : elliptic equation, positive solutions, absence of solutions.
Keywords: Neuman boundary value condition, unbounded domain
