This paper shows that the relevant logics E and Π′ are strongly sound and complete with
regards to a version of the “simplified” Routley-Meyer semantics. Such a semantics for E has …

Relevant logics are a family of non‐classical logics characterized by the behavior of their
implication connectives. Unlike some other non‐classical logics, such as intuitionistic logic …

It is shown how to model propositional constants within the simplified Routley-Meyer
semantics. Various axioms and rules allowing the definition of modal operators, implicative …

Several research that assesses, or assess computer systems has been undertaken in
previous decades. Choosing an appropriate DBMS system in a computer application …

A challenge for relevant logicians is to delimit their area of study. I propose and explore the
definition of a relevant logic as a logic satisfying a variable-sharing property and closed …

Ackermann's motivational spin on his theory of rigorous implication is analyzed and it is
shown to contain en equivalent idea to Plumwood's notion of suppression freedom. The …

An algebraic type of structure is shown forth which is such that if it is a characteristic matrix
for a logic, then that logic satisfies Meyer's weak variable sharing property. As a corollary, it …
