6 - Modal Extensions
from Part II - Modality
Published online by Cambridge University Press: aN Invalid Date NaN
Summary
In this second part of the book, we will consider some modal extensions of the base relevant logics. For this, we will extend the language with modal operators. A relevant modal logic adds additional axioms and rules governing the new modal operators to the base relevant logic. In this chapter, we will cover the axiomatics of relevant modal logics and some matrix techniques for them. In the next chapter (Chapter 7), we will look at their frame theory.
