本文给出对偶余模M°的结构刻划及()°作为逆变函子的左正合性.同时引入余反射余模描述余反射余代数,由此研究余反射余代数的同调性质,证明当char(F)=0时,F[x1,...,xn]°上的Serre猜测是成立的,即F[x1,...,xn]°的有限余生成内射余模均为余自由的. 相似文献

H是Hopf代数,C是H-模余代数.首先利用余积分的概念,诱导C的右H-余模结构,并构造了smash余积余代数C×H,使C×H作为余代数同构于C H.然后,由C的右H-余模结构诱导C的左H0-模结构,令C=C/KerεH0C,则C×H与C有Morita-Takeuchi关系. 相似文献

The aim of this paper is to research the relation among generalized path algebras, pseudo-admissible ordered semigroup algebras and path algebras over algebras. First, the Gabriel theorem for contract pseudo-admissible ordered semigroup algebras is given. Second, a family of pseudo-admissible ordered semigroups is mixed together via the method of generalized path algebras to construct a new pseudo-admissible ordered semigroup as the extended version. Finally, we characterize the path algebra over an algebra in two ways through normal and non-normal generalized path algebras, respectively, over a field. 相似文献

We investigate the comodule representation category over the Morita-Takeuchi context coalgebra Γ and study the Gorensteinness of Γ. Moreover, we determine explicitly all Gorenstein injective comodules over the Morita-Takeuchi context coalgebra Γ and discuss the localization in Gorenstein coalgebras. In particular, we describe its Gabriel quiver and carry out some examples when the Morita-Takeuchi context coalgebra is basic. 相似文献

The purpose of this paper is to present some dual properties of dual comodule.It turns out that dual comodule has universal property (cf.Theorem 2). Since (()~*, ()~O) isan adjoint pair (cf.Theorem 3), some nice properties of functor()~O are obtained. FinallyTheoram 4 provides that the cotensor product is the dual of the tensor product by (M_A 相似文献

In this paper the Parseval theorem for Laplace and Stieltjestransforms which was proved by Yurekli (1989, IMA J. Appl. Math.,42, 241249) for conventional functions is proved forgeneralized functions. The theorem yields some corollaries similarto the corollaries in Yurekli (1989). 相似文献
