Part of the Universitext book series (UTX)


Observational calculi are logical systems similar to the first order predicate calculus; thus it is possible to consider them from the logical point of view. In particular, questions concerning decidability, axiomatizability, and definability can be naturally asked. It appears that observational calculi could and should be studied also in the “pure” symbolic logic; but our question is what is the importance of the logic of observational calculi for AI and, more generally, for computer science.
