摘要：LetHbe a transfer Krull monoid over a finite abelian groupG(for example, rings of integers, holomorphy rings in algebraic function fields, and regular congruence monoids in the domains). Then each nonunita∈Hcan be written as a product of irreducible elements, saya=u1…uk, and the number of factorskis called the length of the factorization. The tL(a) of all possible factorization lengths is
学校意识形态工作计划the t of lengths ofa. It is classical that the systemℒ(H) = {L(a)∣a∈H} of all ts of lengths depends only on the groupG, and a standing conjecture states that converly the systemℒ(H) is characteristic f
