The Workshop on Formal Models of Norm Change will take place at the University of Luxembourg from November 29-30, 2007. Formal models of norm change have been drawing attention since the seminal works of Alchourrón and Bulygin on normative systems, and that of Alchourrón, Gärdenfors and Makinson on the logic of theory change. In order to represent the dynamics of obligations and permissions, several deontic logics have been proposed. However, these systems did not explicitly refer to possible changes in the underlying norms - if norms were mentioned, they were assumed to be invariable. See the Call for Participation for further information.
