Complexity of some modal logics of density (extended version)

Published 15 Jul 2025 in cs.LO | (2507.11238v1)

Abstract: By using a selective filtration argument, we prove that the satisfiability problem of the unimodal logic of density is in $EXPTIME$. By using a tableau-like approach, we prove that the satisfiability problem of the bimodal logic of weak density is in $PSPACE$.
