Florence, Italy November 18-22, 2003 University of Florence Ramifications of Category Theory A Workshop including a featured lecture series by F. W. Lawvere A Workshop on the Ramifications of Category Theory will take place in Florence, Italy, from November 18 to November 22, 2003. The workshop will pay attention not only to issues internal to category theory, and in particular to topos theory, but also to manifold relationships of category theory with topology, logic, philosophy, physics and theoretical computer science, as witnessed by the list of invited speakers. The aim is that of providing a recognition of present-day frontiers of category-theoretic research and a perspective on future research in the field, with emphasis on the foundations of mathematics and the applications of category theory. The workshop is also intended to honor Professor F.W. Lawvere on the 40th anniversary of his Doctoral thesis on Functorial Semantics for Algebraic Theories and to help bring into clearer focus the philosophical consequences of his work, in particular the deep unification of geometry, algebra and logic and of the concepts and tools of these areas of mathematics which have stemmed from it. Professor Lawvere will give a series of lectures, one central topic of which will be quality, in its relation to space and quantity. Intensive and extensive aspects of quality, together with an adjoint characterization of it will be examined. The general goal of his lectures will be to concentrate some essentials from research in algebra and geometry to arrive at precise philosophical formulations as a guide to the pursuit of learning and future research in mathematical sciences.
