Set Theory has a special role in mathematics: on one hand it is the study of infinite sets and their properties, on the other it serves as the foundations for all of mathematics and therefore has philosophical significance. The combinatorial tools developed in the study of infinity have been applied in areas such as: topology, analysis, measure theory, ergodic theory, homological algebra, etc. On the foundational side set theory studies new axioms for mathematics and evaluates their consistency and truth. The Luminy workshops in Set Theory have been taking place since 1990. The goal of these meetings is to present the most important recent advances in set theory and its interactions with other disciplines, and also to promote new promising directions in research. The scientific level of these meetings is very high, we usually have around 10 ICM speakers, 2 ERC grant holders, experts from leading universities around the world, as well as some of the most promising young researchers. These meetings reinforce the attractiveness of France and Europe in this subject and help to keep the set theoretic community together. The program committee chooses 2-3 themes and invites renowned researchers to give mini courses on these topics. It also selects around 60 participants making an effort to maintain geographic, gender, age and thematic diversity. The scientific program is then made by the participants themselves who propose lectures on their recent work.
