Practical description logic systems play an ever-growing role for knowledge representation and reasoning research even in distributed environments. In particular, the often-discus...
Pi is a system for the interactive construction and editing of formal derivations in the calculus of finitary partial inductive definitions. This calculus can be used as a logical ...
e introducing the types and constants of the logic, i.e. its abstract syntax, and axioms describing the inference rules. As a tiny example, consider the following definition of min...
In nonmonotonic reasoning, a default conditional has most often been informally interpreted as a defeasible version of a classical conditional, usually the material conditional...
This paper introduces a nested sequent system for predicate logic. The system features a structural universal quantifier and a universally closed existential rule. One nice conseq...
