In this paper we present methods to generate a Description Logic (DL) theory from a given First Order Logic (FOL) theory, such that each DL axiom is entailed by the given FOL theor...
Abstract. PROTEIN (PROver with a Theory Extension INterface) is a PTTPbased first order theorem prover over built-in theories. Besides various standardrefinements knownformodelelim...
We assume that safety of information stored in a database depends on the reliability of the agents who have performed the insertions in the database. We present a logic S to repres...

Lambda logic is the union of first order logic and lambda calculus. We prove basic metatheorems for both total and partial versions of lambda logic. We use lambda logic to state a...
Partial functions and operators are used extensively in the formal development of programs and thus development methods have to clarify how to reason about them. There are a numbe...
