# reference request – Where are good sources for correspondences in relevant logic?

Relevant logics for entailment have correspondences for a ternary relation $$textit{R}$$ such that $$M,avDash (Ato B)$$ just if $$forall b, c(M,bvDash A Rightarrow M,cvDash B)$$.

Various conditions upon $$textit{R}$$ correspond with, or induce axioms for $$to$$. Some examples are stated in the following Wikipedia article Relevance logic; as an example, $$textit{R}aaa$$ induces the axiom $$(Awedge(Ato B))to B$$.

Where may I find more correspondences, in order to identify the conditions we need upon $$textit{R}$$ to obtain the modal logic identified as $$textit{TW}$$ in (Relevance logic)?1
