Cohomology of Arithmetic Groups and Automorphic Forms Proceedings of a Conference held in Luminy/Marseille, France, May 22-27, 1989

Cohomology of arithmetic groups serves as a tool in studying possible relations between the theory of automorphic forms and the arithmetic of algebraic varieties resp. the geometry of locally symmetric spaces. These proceedings will serve as a guide to this still rapidly developing area of mathematics. Besides two survey articles, the contributions are original research papers.
