Anti-Grand Unification and the Phase Transitions at the Planck Scale in Gauge Theories

This review is devoted to Anti-Grand Unification and to the Multiple Point Model solution of problems of the unification of gauge interactions. According to this model, near the Planck scale there exists a Multiple Critical Point (MCP), where vacua of all fields existing in nature are degenerate. The MCP rules over the evolution of all inverse finestructure constants in the Standard model and beyond it.
