Jca. Barata et Dhu. Marchetti, THE 2-POINT FUNCTION AND THE EFFECTIVE FUGACITY IN DILUTED ISING-MODELS ON THE CAYLEY TREE, Reviews in mathematical physics, 10(6), 1998, pp. 751-773
Some results on the two-point function and on the analytic structure o
f the momenta of the effective fugacity at the origin for a class of d
iluted ferromagnetic Ising models on the Cayley tree are presented.
