基础R0-代数的性质及在L*系统中的应用 总被引:5,自引:1,他引:4
研究了王国俊教授建立的模糊命题演算的形式演绎系统L*和与之在语义上相关的R0-代数,提出了基础R0-代数的观点并讨论了其中的一些性质,在将L*系统中的推演证明转化为相应的R0-代数中的代数运算方面作了一些尝试,作为它的一个应用,证明了L*系统中的模糊演绎定理。 相似文献

本文我们引入了函数类Bδ(G//K)={φ∈L1(G//K)||φ(t)|≤Δ-1(t)(1+t)1-δ,δ>0),对f∈Lp(G//K),1≤p≤∞,和极大算子(?),证明了这类算子是(H∞,s1,L1)型的. 相似文献

本文给出了Oh点群表象中的d2,8(C3v*)完全强场矩阵,并借助于这种矩阵的特征值和特征矢量,建立了CsMgX3:Ni2+(X=Cl,B,I)类晶体的全组态混合EPR理论。应用这一理论,对CsMgCl3晶体中的Ni2+杂质离子的光学吸收谱、基态零场分裂参量D、顺磁g因数、基态Zeeman分裂以及EPR条件(B,hv0)进行了统一的计算。结果与观测非常一致,从而首次对CsMgCl3:Ni2+的光、磁性质作出了统一的理论解释。 相似文献

范畴RMnl上的一个函子 总被引:1,自引:1,他引:0
Let RMnl′ be a category which is equivalent to the category of left R-modules.In this paper,we define afunction F:RMnl→RMnl′ and prove that the functor Fpreserves products,direct limits,injections,surjectios and total esactness.Finally,we show that the functor F is a left-adjoint of the inclusion functor I:RMnl′→RMnl. Hence I:RMnl′ is a renective subcategory of RMnl. 相似文献

. Our group is defined by generators and relations, in terms of double short exact Sequences instead of automorphisms. We establish its relation to Quillen's K1 by dealing with loops in the G-construction. 相似文献

Let Z2 denote a cyclic group of 2 order and Z22 = Z2 ×Z2 the direct product of groups. Suppose that (M, Φ) is a closed and smooth manifold M with a smooth Z22 -action whose fixed point set is the disjoint union of two real projective spaces with the same dimension. In this paper, the authors give a sufficient condition on the fixed data of the action for (M, Φ) bounding equivariantly. 相似文献

Digital Cofibration and Digital Lusternik-Schnirelmann Category in the Sense of Subdivision 下载免费PDF全文
In this paper, using the notion of subdivision, the authors generalize the definition of cofibration in digital topology and show that this kind of cofibration is injective in the sense of subdivision. Meanwhile, they give the necessary condition under which a digital map is a cofibration. Furthermore, they consider the Lusternik-Schnirelmann category of digital maps in the sense of subdivision and give several fundamental homotopy properties about it. 相似文献

It is shown that any countable simple and unperforated partially ordered Abelian group with order unit, paired in an arbitrary way with a compact metrizable Choquet simplex, occurs as the K0group of a simple unital *-algebra which is the inductive limit of a sequence of subhomogeneous *-algebras of a particularly simple form. 相似文献
