Minimal non-relevant logics without the K axiom II. Negation introduced via the unary connective

Gemma Robles
2010 Reports on Mathematical Logic  
In the first part of this paper (RML No. 42) a spectrum of constructive logics without the K axiom is defined. Negation is introduced with a propositional falsity constant. The aim of this second part is to build up logics definitionally equivalent to those displayed in the first part, negation being now introduced as a primitive unary connective. Relational ternary semantics is provided for all logics defined in the paper.
