# Modal logics of sabotage revisited

@article{Aucher2018ModalLO, title={Modal logics of sabotage revisited}, author={Guillaume Aucher and Johan van Benthem and Davide Grossi}, journal={J. Log. Comput.}, year={2018}, volume={28}, pages={269-303} }

Sabotage modal logic was proposed in 2003 as a format for analysing games that modify graphs they are played on. We investigate some model-theoretic and proof-theoretic aspects of sabotage modal logic, which has come to be viewed as an early dynamic logic of graph change. Our first result is a characterization theorem for sabotage modal logic as a fragment of first-order logic which is invariant with respect to a natural notion of ‘sabotage bisimulation’. Next, we offer a sound and complete…

### THE MODAL LOGIC OF STEPWISE REMOVAL

- Computer ScienceThe Review of Symbolic Logic

This work provides a complete Hilbert-style axiomatization for the logic of stepwise removal in a hybrid language enriched with nominals and public announcement operators and analyzes its expressive power and proves a bisimulation characterization theorem.

### Hybrid Sabotage Modal Logic

- 2022

A new hybrid modal logic HSML is introduced for reasoning about sabotage-style graph games with edge deletions, and a complete Hilbert-style axiomatization is provided to extend the completeness analysis to protocol models with restrictions on available edge deletion.

### Satisfiability for relation-changing logics

- Computer Science, PhilosophyJ. Log. Comput.
- 2018

It is shown that relation-changing modal logics, extensions of the basic modal logic with dynamic operators that modify the accessibility relation of a model during the evaluation of a formula, can be translated into hybrid logic and satisfiability is, in general, undecidable.

### Modal Logics with Composition on Finite Forests: Expressivity and Complexity

- Philosophy, Computer ScienceLICS
- 2020

It is shown that ML(|) is as expressive as the graded modal logic GML (on trees) whereas ML(*) is strictly less expressive than GML, a result which is surprising given their relative expressivity.

### Why Propositional Quantification Makes Modal and Temporal Logics on Trees Robustly Hard?

- PhilosophyArXiv
- 2021

It is shown that QCTL restricted to the temporal operator EX is already Tower-hard, which is unexpected as EX can only enforce local properties, and it is proved that the satisfiability problem is AExppol-complete.
