Query: Singular solution of the Liouville equation under perturbation   Small perturbation of the Liouville equation under singular initial data is
considered. An asymptotics of the singular solution is constructed by the
method which is similar to Bogolubov -- Krylov one. The main object is an
asymptotics of the singular lines.
