In a previous paper, the authors investigated the lowersemicontinu-ity properties of two generalizations of the classical Preisach operator; the smoothed Preisach operator and the Krasnoselskii / Pokrovskii (KP) integral hysteresis operators. In particular, it was demonstrated that the output least squares identiication problem for the KP operator is(More)
The catenary degree of an element s of a cancellative commutative monoid S is a nonnegative integer measuring the distance between the irreducible factorizations of s. The catenary degree of the monoid S, defined as the supremum over all catenary degrees occurring in S, has been heavily studied as an invariant of nonunique factorization. In this paper, we(More)
