Transitive Closure Logic: Infinitary and Cyclic Proof Systems

open access: yes, 2018
Transitive closure logic is a known extension of first-order logic obtained by introducing a transitive closure operator. While other extensions of first-order logic with inductive definitions are a priori parametrized by a set of inductive definitions ...

An infinitary treatment of full mu-calculus

open access: yes, 2019
We explore the proof theory of the modal μ-calculus with converse, aka the ‘full μ-calculus’. Building on nested sequent calculi for tense logics and infinitary proof theory of fixed point logics, a cut-free sound and complete proof system for full μ ...
