Preface

A two-week Summer School on “Structures in Lie Theory, Crystals, Derived Functors, Harish-Chandra Modules, Invariants and Quivers” was held at Jacobs University Bremen during 9–22 August 2009 on both the geometric and algebraic aspects of Lie Theory. The participants were mainly from European countries with strong contingents from Germany, Russia, and Israel. Several high-level graduate courses were given, containing recent or original results on topics of particular current interest. The detailed notes of five of these lecture courses are reproduced in this volume. They not only provide a welcome reminder of the content of these courses to the participants, but enable all those who did not attend the meeting to profit from insights of leading specialists into the latest developments in some exciting fields of research. Even those participants who followed the courses attentively may profit from the details presented in this book. Besides the presenters of the graduate courses, some younger researchers were invited to speak at the meeting and to submit a manuscript for publication. Thus the present volume also contains five original articles. All the texts reproduced here were subject to a strict refereeing procedure befitting any mathematical journal.
