This book concerns the theory of unipotent elements in simple algebraic groups over algebraically closed or nite elds, and nilpotent elements in the correspond- ing simple Lie algebras. As a corollary, we obtain a complete set of generic canonical representatives for the unipotent classes of the finite general unitary groups GUn(Fq) for all prime powers q. Our second topic is concerned with unipotent pieces, defined by G. Lusztig in [Unipotent elements in small characteristic, Transform. Groups 10 (), ].

Algebraic groups play much the same role for algebraists as Lie groups play for analysts. This book is the first comprehensive introduction to the theory of algebraic group schemes over fields that includes the structure theory of semisimple algebraic groups, and is written in .   Algebraic groups play much the same role for algebraists as Lie groups play for analysts. This book is the first comprehensive introduction to the theory of algebraic group schemes over fields that includes the structure theory of semisimple algebraic groups, and is written in the language of modern algebraic geometry.

Capable of developing into only one type of cell or tissue. adj able to form only one type of . Unipotent elements play an important role in the theory of discrete subgroups (cf. Discrete subgroup) of algebraic groups and Lie groups. The presence of unipotent elements in a discrete group $\Gamma$ of motions of a symmetric space, having a non-compact fundamental domain of finite volume, is an important tool for studying the structure of.

An element, x, of an affine algebraic group is unipotent when its associated right translation operator, r x, on the affine coordinate ring A[G] of G is locally unipotent as an element of the ring of linear endomorphism of A[G]. (Locally unipotent means that its restriction to any finite-dimensional stable subspace of A[G] is unipotent in the usual ring sense.).

There is a textbook theorem that the categories of unipotent algebraic groups and nilpotent finite-dimensional Lie algebras are equivalent in characteristic zero.

Indeed, the exponential map is an algebraic isomorphism in this case and the group structure can be defined in terms of the Lie algebra structure and vice versa via the Campbell.

It is, for example, explained in paragraph $8$ (Appendix) of the book Unipotent Algebraic Groups, Lecture Notes in Mathematics Volume, by Tatsuji Kambayashi, Masayoshi Miyanishi, and Mitsuhiro Takeuchi, which is accessible online.

Definition of unipotent linear algebraic groups over non algebraically closed fields. 0.The theorems of Berkeley mathematician Marina Ratner have guided key advances in the understanding of dynamical systems.

Unipotent flows are well-behaved dynamical systems, and Ratner has shown that the closure of every orbit for such a flow is of a simple algebraic or geometric form.

In Ratner’s Theorems on Unipotent Flows, Dave Witte Morris provides both an elementary introduction to these.We assume that the reader is familiar with the general theory of algebraic groups and the core theory of unipotent elements.

Nevertheless, in this introduction we shall review the latter, before outlining the content of the thesis. We shall also review more specialist background material as required. Basic facts about unipotent, nilpotent and.
