= Griffiths inequality
{wiki=Griffiths_inequality}
Griffiths' inequality is a result from statistical mechanics and probability theory, specifically relating to the behavior of certain random configurations in lattice systems. The inequality is usually stated in the context of a lattice model of statistical mechanics, notably in the study of spins or percolation. In simple terms, Griffiths' inequality provides a way to compare the probabilities of different configurations in statistical systems, particularly under conditions of positivity or negativity related to interactions among particles (or spins).
