threshold is studied. For the medium having cubic nonlinearity an effective nonlinear conductivity ae and correlation functions … the conductivity ae and correlators at the percolation threshold grow as ae≈h−w, 〈e4〉≈h−γ, 〈j4〉≈h−ζ for h⪡1. Dykhne …'s relations are used to derive important inequalities for the ae and critical exponents. The nonlinear conductivity, correlators …
