Abstract
The phase diagram of the dilute Ashkin-Teller model is investigated wi thin a real-space renormalization scheme. Using two probability distri butions which correspond to the two-spin coupling, K2, dilution and th e four-spin coupling, K4, dilution, a rich variety of phase diagrams a re obtained. The percolation phase diagram is obtained at T = 0. It de scribes a system of two types of links with different concentrations.
