On Halldén Completeness of Modal Logics Determined by Homogeneous Kripke Frames
(Wydawnictwo Uniwersytetu Łódzkiego, 2015)
Halldén complete modal logics are defined semantically. They have a nice characterization as they are determined by homogeneous Kripke frames.
Interpolation in Normal Extensions of the Brouwer Logic
