Computer theorem proving in math [PDF]

open access: yes, 2004
We give an overview of issues surrounding computer-verified theorem proving in the standard pure-mathematical context. This is based on my talk at the PQR conference (Brussels, June 2003)

The expressive power of modal logic with inclusion atoms [PDF]

open access: yes, 2015
Modal inclusion logic is the extension of basic modal logic with inclusion atoms, and its semantics is defined on Kripke models with teams. A team of a Kripke model is just a subset of its domain. In this paper we give a complete characterisation for the

An Application Specific Informal Logic for Interest Prohibition Theory [PDF]

open access: yes, 2011
Interest prohibition theory concerns theoretical aspects of interest prohibition. We attempt to lay down some aspects of interest prohibition theory wrapped in a larger framework of informal logic.

Property Checking Without Invariant Generation

open access: yes, 2020
We introduce a procedure for proving safety properties. This procedure is based on a technique called Partial Quantifier Elimination (PQE). In contrast to complete quantifier elimination, in PQE, only a part of the formula is taken out of the scope of ...

Isabelle/PIDE as Platform for Educational Tools

open access: yes, 2012
The Isabelle/PIDE platform addresses the question whether proof assistants of the LCF family are suitable as technological basis for educational tools.

Interest prohibition and financial product innovation [PDF]

open access: yes, 2011
We give a rough sketch of the Judaic, Greek, Islamic and Christian positions in the matter of interest prohibition during the last few millennia and discuss the way in which interest prohibition is dealt with in Islamic finance, the problems with ...

On the definition of a theoretical concept of an operating system [PDF]

open access: yes, 2010
We dwell on how a definition of a theoretical concept of an operating system, suitable to be incorporated in a mathematical theory of operating systems, could look like.

On computing fixpoints in well-structured regular model checking, with applications to lossy channel systems [PDF]

open access: yes, 2006
We prove a general finite convergence theorem for "upward-guarded" fixpoint expressions over a well-quasi-ordered set. This has immediate applications in regular model checking of well-structured systems, where a main issue is the eventual convergence of

A progression ring for interfaces of instruction sequences, threads, and services [PDF]

open access: yes, 2009
We define focus-method interfaces and some connections between such interfaces and instruction sequences, giving rise to instruction sequence components. We provide a flexible and practical notation for interfaces using an abstract datatype specification

A feasible algorithm for typing in Elementary Affine Logic

open access: yes, 2004
We give a new type inference algorithm for typing lambda-terms in Elementary Affine Logic (EAL), which is motivated by applications to complexity and optimal reduction.
