Here $ G_0 $ is the corresponding group of Lie-type and $ U^ $ the subgroup of $ G_0 $ generated by all root-subgroups corresponding to positive roots. View Show abstract. Abstract In this chapter we will describe the classification of groups G generated by a class of abstract root subgroups. This classification which is relatively long and difficult, works in principal as follows: First one constructs from the group-theoretic conditions a point-line geometry, which is either a polar space, a projective space, a generalized n -gon or a parapolar space. Franz Georg Timmesfeld, Abstract root subgroups and simple groups of Lie type, Monographs in Mathematics, vol. 95, Birkhäuser Verlag, Basel, 2001. MR 1852057 95. Abstract. In this chapter we will discuss some applications of the theory of abstract root subgroups. In §1 we will describe how the classification of certain groups, which are generated by elements acting quadratically on some finite dimensional vector space M quadratic pairs, can be reduced to abstract root subgroups. In fact, this was the main motivation for developing the theory of. Abstract. The notion of a rank one group with abelian unipotent subgroups grew out of the necessity to generalize the concept of k-root subgroups of [Tim91] to the demands of quadratic pairs [Tim99].It is clear that it is not sufficient just to allow SL 2 s for this purpose, since other types of “rank one groups”, for example 2-dimensional classical groups of Witt index 1, arise in the.
abstract groups since a simple Lie group may still have normal subgroups. Just as we study nite simple groups to develop a rm foundation from which to study more complicated compositions, so would we also like to describe simple Lie groups. To extend subgroups and normal subgroups to analogous notions in Lie algebras. Jun 23, 2002 · Download PDF Abstract: We give a method for constructing dense and free subgroups in real Lie groups. In particular we show that any dense subgroup of a connected semisimple real Lie group G contains a free group on two generators which is still dense in G, and that any finitely generated dense subgroup in a connected non-solvable Lie group H contains a dense free subgroup of rank < 2.

The theory of abstract root subgroups is an important tool to study and classify simple classical and Lie-type groups. It is strongly related to the theory of root groups on buildings developed by J. Tits, which in turn extends the theory of root subgroups of Chevalley groups.

New & Forthcoming Titles New & Forthcoming Titles Journals, Academic Books & Online Media Springer. A group is viewed to be one of the simplest and most interesting algebraic structures. The theory of groups has been applied to many branches of mathematics as well as to crystallography, coding theory, quantum mechanics, and the physics of elementary particles. This material is designed to help the user: 1 understand what groups are and why they are important; 2 to identify certain groups. Jan 26, 2007 · Now these Lie-type groups G of B are the simple groups of Lie-type. To allow for quasisimple groups of Lie-type we defined in  groups of type B. An abstract group ~ G is called of type B, if G is generated by subgroups Ar, r A F and there exists a surjective homomorphism s: G ! G with ker s c ZðGÞ such that sjAr: Ar.

|It was already in 1964 [Fis66] when B. Fischer raised the question: Which finite groups can be generated by a conjugacy class D of involutions, the product of any two of which has order 1, 2 or 37 Such a class D he called a class of 3-tmnspositions of G. This question is quite natural, since the.||Finally in §5 we show that each simple group of Lie type in a general sense is generated by a class of abstract root subgroups. The results of this chapter are, if not mentioned otherwise, from [Tim90a], [Tim91], [Tim99] or [Tim00b].|
