Simplified Semantics for Relevant Logics (and some of their rivals)

March 1993

“Simplified Semantics for Relevant Logics (and some of their rivals)” Journal of Philosophical Logic 22 (1993) 481–511.

I show how Priest and Sylvan’s simplified semantics extends from basic relevant logics to a large class of stronger logics. The completeness proof is a little tricky, given the different behaviour of the normal world in the models. This is the first paper from my Ph.D. thesis.
