Split BN-Pairs of Rank at Least 2 and the Uniqueness of Splittings The 2-Modular Reduction of the Steinberg Representation of a Finite Chevalley Group of Type C n On the Restrictions of Modular Irreducible Representations of Algebraic Groups of Type A .

The authors then systematically develop the subgroup structure of finite groups of Lie type as a consequence of the structural results on algebraic groups. This approach will help students to understand the relationship between these two classes of groups. The book covers many topics that are central to the subject, but missing from existing. The sporadic finite simple groups aren't that big! The Monster group is smaller than the alternating group on 50 letters. I think a better place for you to start (rather than wondering about general intuition for very particular objects) would be to look at Griess's Twelve Sporadic freelancerscomic.com recollection is that that book is quite accessible, and it'll let you get a glimpse of what's going on.

Oct 12,  · This cohomological approach carries over to the context of algebraic groups in characteristic p.

In essence, this is where the book Modular Representations of Finite Groups of Lie Type begins. After a brief introduction, Humphreys guides the reader through the some of the major theorems and conjectures in the subject.

Finite groups of Lie type encompass most of the finite simple groups. Their representations and characters have been studied intensively for half a century, though some key problems remain unsolved.

This is the first comprehensive treatment of the representation theory of finite groups of Lie type over a field of the defining prime characteristic.

As a consequence one gets for example the Harish-Chandra theory for irreducible ordinary representations of finite groups of Lie type as special case.

It is intended as a (non-comprehensive) survey covering some. You can write a book review and share your experiences. Other readers will always be interested in your opinion of the books you've read.

Whether you've loved the book or not, if you give your honest and detailed thoughts then people will find new books that are right for them. Oct 31,  · The authors present (with either proof or reference to a proof) those theorems of abstract finite group theory, which are fundamental to the analysis in later volumes in the series.

This volume provides a relatively concise and readable access to the key ideas and theorems underlying the study of finite simple groups and their important freelancerscomic.comon: Rutgers University, New Brunswick, NJ. Building on the background material from algebraic geometry and algebraic groups, the text provides an introduction to more advanced and specialised material.

An example is the representation theory of finite groups of Lie type. The text covers the conjugacy of Borel subgroups and maximal tori, the theory of algebraic groups.Jan 01,  · Split BN-Pairs of Rank at Least 2 and the Uniqueness of Splittings The 2-Modular Reduction of the Steinberg Representation of a Finite Chevalley Group of Type On the Restrictions of Modular Irreducible Representations of Algebraic Groups of Type to Cited by: 8.We establish a fixed point property for a certain class of locally compact groups, including almost connected Lie groups and compact groups of finite abelian width, which act by simplicial isometries on finite rank buildings with measurable stabilisers of points.
