### Resolution for hybrid logics

Stanislovas Norgėla
2011 Lietuvos matematikos rinkinys
We describe a resolution method and a procedure to transform formulae of some pure hybrid logics into their clausal form.  ...  Resolution method become much simpler.  ...  This transformation is the basis for the resolution calculus for modal logic S4 presented in [7] .  ...

### A Principle for Incorporating Axioms into the First-Order Translation of Modal Formulae [chapter]

Renate A. Schmidt, Ullrich Hustadt
2003 Lecture Notes in Computer Science
In this paper we present a translation principle, called the axiomatic translation, for reducing propositional modal logics with background theories, including triangular properties such as transitivity  ...  , Euclideanness and functionality, to decidable logics.  ...  The system combines temporal resolution for the temporal formulae and first-order resolution on the modal formulae.  ...

Renate A. Schmidt, Ullrich Hustadt
2013 Lecture Notes in Computer Science
In this paper we give an overview of results for modal logic which can be shown using techniques and methods from first-order logic and resolution.  ...  Because of the breadth of the area and the many applications we focus on the use of first-order resolution methods for modal logics.  ...  Let ϕ be a modal formula in negation normal form and let N be the clausal form of π sf (ϕ, ǫ) ∧ SF(∆).  ...

### Implementing Temporal Logics: Tools for Execution and Proof [chapter]

I thank them all for their endeavours. Summary We have overviewed a selection of tools for execution and proof within temporal logic.  ...  this work has been supported by funding from the Engineering and Physical Sciences Research Council (EPSRC) 1 , and has involved collaboration with a variety of outstanding colleagues from within the Logic  ...  Implementations Clausal Temporal Resolution The essential complexity in carrying out clausal temporal resolution is implementing the temporal resolution rule itself.  ...

### Modal resolution in clausal form

Patrice Enjalbert, Luis Farinas del Cerro
1989 Theoretical Computer Science
A method, called Modal Resolution and inspired by Robinson's resolution method for classical logics, is presented for the system K and then extended to Q, T, S4, epistemic logic, and S5.  ...  This paper concerns the question of automated deduction methods for modal logic.  ...  Acknowledgment We thank Yves Auffray and Jean Jacques Hebrard for many critical discussions on an earlier version of the paper.  ...

### A Calculus for Automatic Verification of Petri Nets Based on Resolution and Dynamic Logics

Cláudia Nalon, Bruno Lopes, Gilles Dowek, Edward Hermann Haeusler
2015 Electronical Notes in Theoretical Computer Science
Dynamic Logics (DL) are a family of modal logics where each modality corresponds to a program.  ...  This works presents a resolution-based method for Petri-PDL, a DL where programs are replaced by Petri Nets.  ...  (PL), (K), and (Du), together with the inference rules (Sub), (MP), and (GEN), correspond to the usual axiomatisation for normal modal logics.  ...

### Mechanised Reasoning and Model Generation for Extended Modal Logics [chapter]

Renate A. Schmidt, Ullrich Hustadt
2003 Lecture Notes in Computer Science

### Optimised Functional Translation and Resolution [chapter]

Ullrich Hustadt, Renate A. Schmidt, Christoph Weidenbach
1998 Lecture Notes in Computer Science
It maps normal propositional modal logics into a class of path logics.  ...  Path logics are clausal logics over the language of the monadic fragment of sorted first-order logic with a special binary function symbol for defining accessibility.  ...  While for the basic modal logic, the classes of non-provable formulae (in the second column) are not harder than the classes of provable formulae, we see a noticeable difference between kt dum n, kt poly  ...

### A new methodology for developing deduction methods

Renate A. Schmidt
2009 Annals of Mathematics and Artificial Intelligence
This paper explores the use of resolution as a meta-framework for developing various, different deduction calculi. In this work the focus is on developing deduction calculi for modal dynamic logics.  ...  The approach is based on the translation of reasoning problems in modal logic to first-order clausal form and using a suitable refinement of resolution to construct and mimic derivations of the desired  ...  I also thank the reviewers for valuable comments. The research has been supported by UK EPSRC grants EP/D056152/1 and EP/F068530/1.  ...

### Simulation and Synthesis of Deduction Calculi

Renate A. Schmidt
2010 Electronical Notes in Theoretical Computer Science
This paper gives an overview of two methods for automatically or semi-automatically generating deduction calculi from the semantic specification of a logic.  ...  One approach is based on simulating deduction approaches with techniques of automated reasoning and first-order resolution.  ...  This is illustrated in [24] for extensions of the basic modal logic K .  ...

1995 Mathematical Reviews
Summary: “We present a resolution method for a nonmonotonic multimodal logic called hypothesis theory. As we define a reso- lution method, we need modal formulas to be in clausal normal form.  ...  But an important problem with modal logic is that there is no such simple normal form as in classical logic. So we propose an original clausal transformation for modal formulas.  ...

1999 Mathematical Reviews
The presented resolution rules are split into four groups: initial resolution, modal resolution, step resolution, and temporal resolution.  ...  In the second part the author introduces the idea of a modal logic of agency. He goes on to discuss Pérn’s modal logic of agency, Brown’s logic of ability, and Belnap’s STIT-theory.  ...
