Abstract
In this paper we apply combinatorial approach and graph expansion to c alculate multispin correlation function of the Ising model on Bethe-ty pe lattice. The result indicates no existence of long range correlatio n at any finite temperature which implies that no finite temperature p hase transition occurs.
