Abstract

The second postulate of Katsuno and Mendelzon characterizes irrelevant updates. We show that the postulate has to be modified, if nonmonotonic assumptions are considered. Our characterization of irrelevant updates is based on a dependency framework, which provides an alternative semantics of multidimensional dynamic logic programming.
