Statistical Physics and Interdisciplinary Applications

Correlations play an important role in statistical physics. In 1967 Griffiths derived some simple inequalities between correlations in a ferromagnetic system where interacting elements tend to have the same position in the configuration space. I will introduce these inequalities along with some generalizations to see how one can apply them to other interacting systems. References: [1] R. B. Griffiths, 1967. [2] C. M. Fortuin, P. W.
