  1. Graded modalities. III (the completeness and compactness of s40).M. Fattorosi-Barnaba & C. Cerrato - 1988 - Studia Logica 47 (2):99 - 110.
    We go on along the trend of [2] and [1], giving an axiomatization of S4 0 and proving its completeness and compactness with respect to the usual reflexive and transitive Kripke models. To reach this results, we use techniques from [1], with suitable adaptations to our specific case.

  • General canonical models for graded normal logics (graded modalities IV).C. Cerrato - 1990 - Studia Logica 49 (2):241 - 252.
    We prove the canonical models introduced in [D] do not exist for some graded normal logics with symmetric models, namelyKB°, KBD°, KBT°, so that we define a new kind of canonical models, the general ones, and show they exist and work well in every case.
