本文进一步发展共形几何代数,从代数和几何两个角度对共形几何代数中由幂零向量生成的分阶单项式的代数性质和几何解释进行深入探讨,包括各种维数的球面和平面定向的代数刻画、长括号的三角学、角度和方向的幂零单项式分阶表示、幂零单项式各个分阶的几何意义等.这些结果有助于理解高层次符号代数运算背后的几何意义,以及共形几何代数简化符号几何计算的内在机制. 相似文献

通过对模糊逻辑命题演算形式系统L*的代数语义——R0代数的研究,给出了R0代数簇的完整分类,并利用L*系统与幂零极小逻辑(NML)的等价性,由系统L*是可代数化逻辑出发,得到与R0代数真子簇对应的L*系统的全部公理化扩张,文中所用的方法用样适用于其他满足逆序对合关系的逻辑的扩张,具有较好的扩展性。 相似文献

For integral table algebras with integral table basisT, we can consider integralR-algebraRT over a subringR of the ring of the algebraic integers. It is proved that anR-algebra isomorphism between two integral table algebras must be an integral table algebra isomorphism if it is compatible
with the so-called normalizings of the integral table algebras 相似文献

We give algebraic and geometric classifications of 4-dimensional complex nilpotent terminal algebras. Specifically, we find that, up to isomorphism, there are 41 one-parameter families of 4-dimensional nilpotent terminal (non-Leibniz) algebras, 18 two-parameter families of 4-dimensional nilpotent terminal (non-Leibniz) algebras, 2 three-parameter families of 4-dimensional nilpotent terminal (non-Leibniz) algebras, complemented by 21 additional isomorphism classes (see Theorem 13). The corresponding geometric variety has dimension 17 and decomposes into 3 irreducible components determined by the Zariski closures of a one-parameter family of algebras, a two-parameter family of algebras and a three-parameter family of algebras (see Theorem 15). In particular, there are no rigid 4-dimensional complex nilpotent terminal algebras. 相似文献

For modular group algebras over an arbitrary field we define new type of blocks: blocks with nilpotent extensions, and describe their source algebras. To do it, a general pattern is proposed for relations between the source algebra of a block and the source algebra of a block appearing in its decomposition in a suitable extension of the field of coefficients. 相似文献

Novikov algebras and Novikov structures on Lie algebras 总被引:1,自引:0,他引:1
We study ideals of Novikov algebras and Novikov structures on finite-dimensional Lie algebras. We present the first example of a three-step nilpotent Lie algebra which does not admit a Novikov structure. On the other hand we show that any free three-step nilpotent Lie algebra admits a Novikov structure. We study the existence question also for Lie algebras of triangular matrices. Finally we show that there are families of Lie algebras of arbitrary high solvability class which admit Novikov structures. 相似文献

We find examples of nilpotent n-Lie algebras and prove n-Lie analogs of classical group theory and Lie algebra results. As an example we show that a nilpotent ideal I of class c in a n-Lie algebra A with A/I 2 nilpotent of class d is nilpotent and find a bound on the class of A. We also find that some classical group theory and Lie algebra results do not hold in n-Lie algebras. In particular, non-nilpotent n-Lie algebras can admit a regular automorphism of order p, and the sum of nilpotent ideals need not be nilpotent. 相似文献
