FINITE GROUPS OF UNITS AND THEIR COMPOSITION FACTORS IN THE INTEGRAL GROUP RINGS OF THE GROUPS PSL(2, q)
نویسنده
چکیده
Let G denote the projective special linear group PSL(2, q), for a prime power q. It is shown that a finite 2-subgroup of the group V(ZG) of augmentation 1 units in the integral group ring ZG of G is isomorphic to a subgroup of G. Furthermore, it is shown that a composition factor of a finite subgroup of V(ZG) is isomorphic to a subgroup of G.

Rational Group Algebras of Finite Groups: from Idempotents to Units of Integral Group Rings
We give an explicit and character-free construction of a complete set of orthogonal primitive idempotents of a rational group algebra of a finite nilpotent group and a full description of the Wedderburn decomposition of such algebras. An immediate consequence is a well-known result of Roquette on the Schur indices of the simple components of group algebras of finite nilpotent groups. As an appl...
متن کاملThe Brauer group of Burnside rings
The Brauer group of a commutative ring is an important invariant of a commutative ring, a common journeyman to the group of units and the Picard group. Burnside rings of finite groups play an important rôle in representation theory, and their groups of units and Picard groups have been studied extensively. In this short note, we completely determine the Brauer groups of Burnside rings: they van...
متن کاملFree Subgroups in Linear Groups and Group Rings
This paper is an extension of the talk I gave at the International Conference on Non-Commutative Rings, Group Rings, Diagram Algebras and Applications at the University of Madras in December 2006. It discusses certain techniques used to prove the existence of free subgroups in linear groups and in the unit group of integral group rings of finite groups. Its main focus is recent joint work with ...
متن کاملFinite Abelian Groups and Character Sums
These are some notes I have written up for myself. I have compiled what I feel to be some of the most important facts concerning characters on finite abelian groups, especially from a number theoretic point of view. I decided to distribute these because I couldn’t find a single reference that covered everything that I thought was relevant to the material I will discuss on Wednesday. Of course, ...
متن کاملChange of Species Diversity in Vascular Plants Across Ecological Species Groups
Biodiversity plays a crucial role in stability and productivity of natural ecosystem. The main goal of this research was to classify ecological groups in steppe rangeland and investigate their relationships with plant diversity indices. Therefore, fifty different Land Unit Tracts (LUT) were identified in Khod-Neuk basin, Yazd province, Iran, in 2010. Vegetation and soil samples were taken in th...
