We present tableau calculi for the logics $\gdj_k$ ($k\geq 2$) semantically characterized by the classes of Kripke models built on finite $k$-ary trees. Our tableau calculi use the signs $\T$ and $\F$, some tableau rules for Intuitionistic Logic and two rules formulated in a hypertableau fashion. We prove the Soundness and Completeness Theorems for our calculi. Finally, we use them to prove the main properties of the logics $\gdj_k$, in particular their constructivity and their decidability.

Abstract

We present tableau calculi for the logics $\gdj_k$ ($k\geq 2$) semantically characterized by the classes of Kripke models built on finite $k$-ary trees. Our tableau calculi use the signs $\T$ and $\F$, some tableau rules for Intuitionistic Logic and two rules formulated in a hypertableau fashion. We prove the Soundness and Completeness Theorems for our calculi. Finally, we use them to prove the main properties of the logics $\gdj_k$, in particular their constructivity and their decidability.
