We study two classes of Artinian modules called co-Buchsbaum modules and generalized co-Cohen-Macaulay modulesSome basic properties and characterizations of the
Let R be a commutative Noetherian ring and M a finite (i.e., finitely generated) R-module. The grade of M was introduced by Rees as the least integer l≥ 0 such
棉花是喜光作物,棉花单叶光补偿点是750-1000 lux,光饱和点是7-8万lux,适应在充足的光照条件下生长。棉花生长发育过程中,花铃期是棉花产量、品质形成的关键时期,也是对外界环境反应最敏感的时期。近年来,随着全球气候变化及我国棉花生产区域布局的调整,花铃期寡照时有发生,给我国棉花高产、优质栽培带来了不利影响。棉花生长发育状况与棉花产量品质的形成密切相关,因此,研究弱光条件下棉花生长发育动态
A classification of SL2(F) (F a field) as a rank one group with abelian diagonal subgroup, possessing a quadratic module, is given.
Let p be a prime number. In this paper, the author sets up a canonical correspondence between polynomial functions over Z/p2Z and 3-tuples of polynomial functio
In this paper, we answer some questions raised by Fine et al. In [1]and prove that every locally finite group is 1-(commutative-transitive).
Let 2 be a variety of algebras with involution * over a field of characteristic zero and cn(V, *) the corresponding sequence of *-codimensions. Here,we characte
