A Foundational View on Integration Problems
The integration of reasoning and computation services across system and
language boundaries is a challenging problem of computer science. In this
paper, we use integration for the scenario where we have two systems that we
integrate by moving problems and solutions between them. While this scenario is
often approached from an engineering perspective, we take a foundational view.
Based on the generic declarative language MMT, we develop a theoretical
framework for system integration using theories and partial theory morphisms.
Because MMT permits representations of the meta-logical foundations themselves,
this includes integration across logics. We discuss safe and unsafe integration
schemes and devise a general form of safe integration

The many-valued theorem prover 3TAP. 3rd. edition
This is the 3TAP handbook. 3TAP is a many-valued tableau-based
theorem prover developed at the University of Karlsruhe.
The handbook serves a triple purpose: first, it documents the
history and development of the prover 3TAP; second, it provides a
user\u27s manual, and third it is intended as a reference manual for
future developers, including porting hints.
This version of the handbook describes 3TAP Version 3.0 as of
September 30,1994
Dedukti: a Logical Framework based on the -Calculus Modulo Theory
Dedukti is a Logical Framework based on the -Calculus Modulo
Theory. We show that many theories can be expressed in Dedukti: constructive
and classical predicate logic, Simple type theory, programming languages, Pure
type systems, the Calculus of inductive constructions with universes, etc. and
that permits to used it to check large libraries of proofs developed in other
proof systems: Zenon, iProver, FoCaLiZe, HOL Light, and Matita
