The function (1.1) and especially its derivatives at t = 0 define important quantities in quantum statistical mechanics. Proving positive definiteness would lead to interesting relations among them. There have been several attempts to prove this conjecture but proofs have only been obtained under additional assumptions on H and K. A summary of such results… (More)
