密度定理 meaning in Chinese

density theorem

At the same time we abroad some results of [ 1 ] . by introducing the concept of [ 3 ] about gr - linearly compact discrete ( gr - l . c . d . ) , we have proved density theorem in semigroup graded module , and gain a equivalence : for , sqa is gr - injection if and only if for , rq is gr - linearly compact discrete ( gr - l . c . d . )
第四部分证明了半群分次模上的密度定理，并给出了一个等价条件，即：对任意的s s ， _ sq _ a是分次内射的，当且仅当对任意的， _ rq _是分次线性离散紧的，记作： gr ? 1 . c . d
