Qualitative and numerical analysis of the cosmological model based on the asymmetric scalar dublet with minimum connections. III. Multifunction factor and character of singular points

Based on the qualitative and numerical analysis of the cosmological model based on an asymmetric scalar doublet of nonlinear minimally interacting scalar fields, classical and phantom, the behavior of the model near hypersurfaces of zero energy is revealed. The influence of the multiply connected factor of the phase space of a dynamic system, which is a consequence of the nonanalyticity of the coefficients of an autonomous system of differential equations, is discussed. Identified the nature of all singular points.
