The divergence of the perturbation expansion and the skeleton expansion were proved. The existence of a phase transition in the lattice version of Reggeon field theory was proved,and the structure of the ground state was investigated. A new method to calculate parameters and critical properties of lattice field theories based on the strong coupling expansion of renormalization group equations was constructed.
