finite index [计] 有限指数, 有穷指数
- Let I( G) denote greatest index of maximal subgroups of a finite group G. In this paper the structures of G for I( G)=2,3, I( G)≤7 and≤11 are obtained, respectively.
该文考察了极大子群指数上限对群结构的影响,刻划了指数上限分别等于2和3,不大于7和不大于11的有限群类的结构。 - This article studies the effect the normal index of common subgroup has on the nature of its own group so as to obtain a series of solvable and super-unsolvable full-prerequisite conditions of finite
本文研究一般子群的正规子数对群本身性质的影响,由此得出一系列有限群可解和超可解的充分必要条件. - According to their accuracy, efficiency and complexity, we discussed the numerical methods( finite element method and finite difference method) and the approximate methods( including effective
依据方法的计算精确度、算效率和计算复杂度等因素,对有限元法和有限差分法这两种数值分析方法以及有效指数法和频谱指数法等近似方法进行讨论。
