ON BEURLING INEQUALITY IN TERMS OF THERMAL POWER

Beurling's inequality is proved to have an interpretation in terms of ingredients that do not depend on the effective numerical contribution of transition probabilities of circuit processes (those processes whose transition law is expressed by a denumerable class of directed weighted circuits). Connections with reversibility for S(k)-state, k greater-than-or-equal-to 2, circuit processes, where S is a denumerable set, are revealed.
