Results of qualitive analysis of invariant solutions of distributied models for nonideal adsorbate layer's equilibrium states

This paper contains the results of qualitive analysis of a certain class of invariant solutions of the distributed model of equilibrium state of nonideal adsorbate monolayer. Subregions of existence, uniqueness and multiplicity of solutions, that described superstructures $C(2\times2)/(100)$, $P(1\times2)/(100)$, $(3\times\sqrt3)^*R30^0$, $(3\times\sqrt3)R30^0$ are defined in the region of possible parameter values. Qualitively different dependences of the layer chemical potential from the density of layer are constructed numerically.
