A 2-set-up Routley-Meyer Semantics for the 4-valued Relevant Logic E4 [PDF]
, 2016 The logic BN4 can be considered as the 4-valued logic of the relevant conditional and the logic E4, as the 4-valued logic of (relevant) entailment. The aim of this paper is to endow E4 with a 2-set-up Routley-Meyer semantics.
