It is different from propositional logic which lacks quantifiers. Predicate Logic We now turn our attention to a generalization of propositional logic, called “predi-cate,” or “ﬁrst-order,” logic. Predicates are functions of zero or more variables that return Boolean values. Thus predicates can be true sometimes and false sometimes, depending on the values of their arguments. 2021-01-13 · What Is Predicate Logic A predicate is a statement or mathematical assertion that contains variables, sometimes referred to as predicate variables, and may be true or false depending on those variables’ value or values. A predicate symbol represents a predicate for objects and is notated P (x, y), Q (z),…, where P and Q are predicate symbols. A logical symbol represents an operation on predicate symbols and is notated ↔, ~,→,∨, or ∧ A term can contain individual constants, individual variables, and/or functions.

The letter W, for example, might stand for the predicate of being wise.

In mathematics, a predicate is either a relation or the boolean-valued function that amounts to the characteristic function or the indicator function of such a relation. A function P: X→ {true, false} is called a predicate on X. I'm studying axiomatic set theory and even though I know some predicate logic I still struggle to understand some symbolizations, such as: Union axiom: $(\forall x)(\exists y)(\forall u)(u \in y \iff (\exists v)[v\in x \land u\in v])$ This axiom is no SO hard but I still take a little to understand what it says, when symbols should facilitate the understanding of definitions etc. Predicate calculus gives the underpinnings to the languages of logic programming, such as Prolog. Predicate calculus is increasingly used for specifying the requirements of computer applications. In the area of proving program correctness, predicate calculus allows one to precisely state under which conditions a program gives the correct output. 4 1.5 Quantifiers & Predicate Logic Course Home Syllabus Readings Lecture Slides In-Class Questions Assignments Exams Unit 1: Proofs 1.1 Intro to Proofs; 1 Predicate Logic • Terms represent specific objects in the world and can be constants, variables or functions. • Predicate Symbols refer to a particular relation among objects.
