In physics and mathematics, the Golden–Thompson inequality, proved independently by and , says that for Hermitian matrices ''A'' and ''B'', : where tr is the trace, and ''e''''A'' is the matrix exponential. This trace inequality is of particular significance in statistical mechanics, and was first derived in that context. used the Kostant convexity theorem to generalize the Golden–Thompson inequality to all compact Lie groups. ==References== * * J.E.
