摘要: 设m,n是两个任意取定的正整数, 通过引入(m,n)遗传环的概念, 利用函子的正合性方法, 给出(m,n)投射模和(m,n)遗传环的一些等价刻画.

关键词: (m,n)投射模, (m,n)内射模, (m,n)遗传环

Abstract: Let m,n be two arbitrary  positive integers. By introducing the concept of (m,n)hereditary rings, and using the exact method of functor, we gave some characterizations of (m,n)projective modules and (m,n)hereditary rings.

Key words: (m,n)projective module, (m,n)injective module, (m,n)hereditary ring
