A compilation of papers presented at the 2001 European Summer Meeting of the Association for Symbolic Logic Logic Colloquium '01 includes surveys and research articles from some of the world's preeminent logicians. Two long articles are based on tutorials given at the meeting and present accessible expositions of research in two active areas of logic geometric model theory and descriptive set theory of group actions. The remaining articles cover seperate research topics in many areas of mathematical logic including applications in Computer Science Proof Theory Set Theory Model Theory Computability Theory and aspects of Philosophy. This collection will be of interest not only to specialists in mathematical logic but also to philosophical logicians historians of logic computer scientists formal linguists and mathematicians in the areas of algebra abstract analysis and topology. A number of the articles are aimed at non-specialists and serve as good introductions for graduate students.
