The two volumes in this advanced textbook present results, proof
methods, and translations of motivational and philosophical
considerations to formal constructions. In this Vol. I the author
explains preferential structures and abstract size. In the associated
Vol. II he presents chapters on theory revision and sums, defeasible
inheritance theory, interpolation, neighbourhood semantics and deontic
logic, abstract independence, and various aspects of nonmonotonic and
other logics.
In both volumes the text contains many exercises and some solutions, and
the author limits the discussion of motivation and general context
throughout, offering this only when it aids understanding of the formal
material, in particular to illustrate the path from intuition to
formalisation. Together these books are a suitable compendium for
graduate students and researchers in the area of computer science and
mathematical logic.
