This book is based on two series of lectures given at a summer school on algebraic combinatorics at the Sophus Lie Centre in Nordfjordeid, Norway, in June 2003, one by Peter Orlik on hyperplane arrangements, and the other one by Volkmar Welker on free resolutions. Both topics are essential parts of current research in a variety of mathematical fields, and the present book makes these sophisticated tools available for graduate students.

Peter Orlik is THE expert on arrangements, and Volkmar Welker an excellent mathematician of the younger generation The Nordfjordeid summer school consistently offer high quality

Autorentext

Orlik has been working in the area of arrangements for thirty years. Lectures on this subject include CBMS Lectures in Flagstaff, AZ; Swiss Seminar Lectures in Bern, Switzerland; and Summer School Lectures in Nordfjordeid, Norway, in addition to many invited lectures, including an AMS hour talk.

Welker works in algebraic and geometric combinatorics, discrete geometry and combinatorial commutative algebra. Lectures on the topic of the book include Summer School on Topological Combinatorics, Vienna and Summer School Lectures in Nordfjordeid, in addition to several invited talks.
