Scientific paper

The phase variables method is used in a description of the viscous Robertson-Walker universe's dynamics, and the connection between strong energy condition violence and universe behavior near a singularity is discussed. It is stressed that a dynamical description of the cosmological evolution connects singularities with critical points of the Poincare hemisphere equator. New singularities are strongly connected with violation of the strong energy condition.
