The Expressive Power of Modal Dependence Logic

... modal logic a team is just a set of states in a Kripke model. Modal dependence logic extends standard modal logic with team semantics by modal dependence atoms, =(p1 , . . . , pn , q). The intuitive meaning of the formula =(p1 , . . . , pn , q) is that within a team the truth value of the propositio ...

A Proof of Cut-Elimination Theorem for U Logic.

... To make the two systems more comparable, Ardeshir and Vaezian in [1], introduced a modified version of mentioned axiomatization, and called it GBPC*. They also excluded connective ← from B and called the new system B’. They justified this action, by mentioning the main goal of Sambin’s Basic logic, ...

PROVING UNPROVABILITY IN SOME NORMAL MODAL LOGIC

... persuaded that these schemata cannot be restricted to some fixed k. For instance, take RK . An easy induction shows that if we restrict RK to some R(k) then all K a-deducible formulae would be refuted in trees in which every node has no more than k branches. But then the K-unprovable formula _ Altn ...
