Abstract
The random cluster model of Kasteleyn and Fortuin, which comprises the Ashkin-Teller-Potts model, the Ising model and the bond percolation problem, is solved on a Cayley tree. The solution is discussed both on a whole tree including the surface and in the interior of a tree. Emphasis is put on including several external fields into the model. Phase transitions and phase diagrams are investigated extensively.
