一个原子幺半群是长度阶乘的,如果任何元素的每两个不同的分解有不同的分解长度。给出了长阶乘Krull幺半群的类群和素因子在类中的分布。
An atomic monoid is length-factorial if each two distinct factorizations of any element have distinct factorization lengths. We provide a characterization of length-factorial Krull monoids in terms of their class groups and the distribution of prime divisors in the classes.
