Logical approaches to deontic reasoning: From basic questions to dynamic solutions

The development of deontic logic has opened new possibilities for the mathematical analysis of norms. This article tackles the description of large families of deontic systems that attempt to formalize such-and-such idea of juridical notions like obligation. It also introduces a modal logic based on actions for studying deontic reasoning within the context of a dynamic logic. © 2008 Wiley Periodicals, Inc.
