[Apologies for multiple copies of this message.] Second announcement -- Meeting on THEORY AND APPLICATIONS OF QUANTALES Department of Mathematics Instituto Superior Técnico Lisboa, Portugal July 16 - 18, 2002 Quantales are ordered semigroups that generalize locales and also play the role of noncommutative spaces. They have been studied in several contexts, ranging from operator algebras and category theory to logic and computer science. The meeting is meant to be quite informal. Its aim is to bring together researchers who are interested in various aspects of quantales, in order to develop a broader understanding of the field both through talks and informal discussion. Updated information about the meeting, including a registration form, can be found at http://www.math.ist.utl.pt/~pmr/Q-meeting/ . We ask all those intending to participate to register as soon as possible, and in any case by June 17. More detailed information will be sent after June 17 to those who meanwhile have registered.
