Predicate Logic. a branch of mathematical logic that studies the laws of logic common for any domain of objects (containing at least one object) with predicates (that is, properties and relations) stipulated for these objects. As a result of formalization, predicate logic takes the form of different calculi.

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. • Sentences represent facts, and are made of of terms, quantifiers and 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. First-order logic—also known as predicate logic, quantificational logic, and first-order predicate calculus—is a collection of formal systems used in mathematics, philosophy, linguistics, and computer science. Predicate Logic is an extension of Propositional Logic not a replacement. It retains the central tenet of Propositional Logic: that sentences express propositions and propositions denote truth-conditions. The difference between these logics is that the basic building blocks of Predicate Logic are much like the building blocks of a sentence in a PREDICATE LOGIC Predicate Instantiated/Domain A predicate instantiated (where variables are evaluated in specific values) is a proposition.

Abstract: The subject of this thesis is the presentation and  The main topics of the course are the completeness theorems of propositional and predicate logic and Gödel's incompleteness theorems.

Something is being predicated of something. That is, something is being said about something. We focused on this when we studied categorical propositions a while ago. We can show the variety of ways that something can be said about something using the symbols of propositional logic.

In general, it can be said that predicate logic takes us from those logical relations that hold between sentences to those that hold within a sentence. We will now examine in … Predicate Logic . Predicate Logic deals with predicates, which are propositions, consist of variables. Predicate Logic - Definition. A predicate is an expression of one or more variables determined on some specific domain.

Predicate Logic. Predicate logic, first-order logic or quantified logic is a formal language in which propositions are expressed in terms of predicates, variables and quantifiers. It is different from propositional logic which lacks quantifiers.

Van Beek. 2/29 Outline Predicate Logic Learning goals Introduction and Motivation Elements of Predicate Logic Predicate Logic Adds the following to Propositional Logic Predicates / Propositional Functions Rather than propositions which are true/false, use Predicates, a.k.a. Propositional Functions which are true / false Logic Notation Defined to be Truthiness Propos.

Sentences in first-order predicate logic can be usefully interpreted as programs. In this paper the operational and fixpoint semantics of predicate logic programs 

• Sentences represent facts, and are made of of terms, quantifiers and predicate symbols. Predicate calculus gives the underpinnings to the languages of logic programming, such as Prolog.
