Rich Chapter 5 Predicate Logic - Computer Science
... These examples illustrate two points. The first is fairly specific. It is that, although class and superclass memberships are important facts that need to be represented, those memberships need not be represented with predicates labeled instance and isa. In fact, in a logical framework it is usually ...

Completeness in modal logic - Lund University Publications
... ordered triple < W, R, V > where W and R are as before, and V is an assignment of the truthvalues 1 and 0 to each atomic formula at every world in W. A formula Φ is true in a model iff it has value 1 in every world in W for some valuation V. Φ is valid in a frame iff it is true in every model based ...

Chapter 2 Propositional Logic
... Why the greek letters in clause ii)? Well, it wouldn’t be right to phrase it, for example, in the following way: “if P and Q are wffs, then ∼P and (P →Q) are also wffs”. That would be too narrow, for it would apply only in the case of the sentence letters P and Q. It wouldn’t apply to any other sent ...

Introduction to Syntax Level 1 Course
... Patterns, the sentence formula is arranged in the unmarked word order. • If we look at all the word order alternations of a sentence as a set of options (=a category), one of the members of this set is unmarked. • Unmarked word order is the word order which is most widely used, and which ...

Mathematical Logic. An Introduction

A symbol set is sometimes called a type because it describes the type of structures which will later interpret the symbols. We shall denote variables by letters like x, ...
