James E. Humphreys is presently Professor of Mathematics at the University of Massachusetts
at Amherst. Before this, he held the posts of Assistant Professor of Mathematics at the …

… In this graduate textbook Professor Humphreys presents a concrete and up-todate introduction
to the theory of Coxeter groups. He assumes that the reader has a good knowledge of …

This book is designed to introduce the reader to the theory of semisimple Lie algebras over
an algebraically closed field of characteristic 0, with emphasis on representations. A good …

… Humphreys [125, $9 then defines an abstract root system in a finite dimensional euclidean
space E over R, with inner product denoted (A, u), to be a finite set q of vectors spanning E …

P-glycoprotein (Pgp) affects the absorption, distribution, and clearance of a variety of
compounds. Thus, identification of compounds that are Pgp substrates can aid drug candidate …

Membrane permeability and P-glycoprotein (Pgp) can be limiting factors for blood-brain barrier
penetration. The objectives of this study were to determine whether there are differences …

Provides a useful exposition of results on the structure of semisimple algebraic groups over
an arbitrary algebraically closed field. After the fundamental work of Borel and Chevalley in …

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 …

Because modulation of P-glycoprotein (Pgp) through inhibition or induction can lead to drug-drug
interactions by altering intestinal, central nervous system, renal, or biliary efflux, it is …

Dolutegravir (DTG; S/GSK1349572) is a potent HIV-1 integrase inhibitor with a distinct resistance
profile and a once-daily dose regimen that does not require pharmacokinetic boosting. …
