Correlations equalities and some upper bounds for the critical
temperature for spin one systems    [PDF]

F. C. Sá Barreto, A. L. Mota

Starting from correlation identities for the Blume-Capel spin 1 systems and using correlation inequalities, we obtain rigorous upper bounds for the critical temperature.The obtained results improve over effective field type results.
