Completeness Theorem for a First Order Linear-time Logic Zoran Ognjanoviæ We describe a first order temporal logic over the natural numbers time. It is well known that the corresponding set of all valid formulas is not recursively enumerable, and that there is no finitistic axiomatization. We present an infinitary axiomatization which is sound and complete with respect to the considered logic.

p p. 122-125 Fuzzy Database Query Languages and Their Relational Completeness Theorem Y. Takahashi Two fuzzy database query languages are proposed. They are used to query fuzzy databases that are enhanced from relational databases in such a way that fuzzy sets are allowed in both attribute values and truth values. A fuzzy calculus query language is constructed based on the relational calculus, and a fuzzy algebra query language is also constructed based on the relational algebra. In addition, a fuzzy relational completeness theorem such that the languages have equivalent expressive power is proved.

The first is classical higher-order logic, with relational quantification of finitely high type; the second system is a predicative fragment thereof with quantification over functions between types, but not over arbitrary relations.

Committee in charge: Richard Montague, Charmain, Alfred Horn, Donald Kalish, Abraham Robinson, Robert Stockwell.

The specific problem with which it successfully deals is a precise formalization of (first-order) quantificational tense logic wherein both an appropriate formal semantics is developed and a meta-mathematically consistent and complete axiomatization for that semantics given. The formalization of quantificational tense logic herein presented adheres to all the canons o£ logical rigor by being carried out entirely as a definitional extension of (Zermelo-Fraenkel) set theory. Model-theoretical techniques are utilized in the semantics given and the notion of a history is formally developed as the tense-logical analogue of the notion of a model for standard first-order logic with identity. Corresponding to the key semantical concept of satisfaction (and consequently of truth) in a model, by means of which the central standard notion of

Understand how to use interpretations and models. Be able to give simple proofs from the axioms. Understand the importance of consistency and completeness. Pre-requisites: Dependent Courses: None Course Description: The course concentrates on one of the most important results of 20th century logic, Gödel's Completeness Theorem for Predicate Logic. This theorem links two fundamental concepts of Mathematics, truth and provability, and provides deep insights into ways of mathematical thinking. Prospective students should enjoy abstract ideas and have the ability to understand mathematical proofs of the type which occur in Pure Mathematics.

CTK Exchange Front Page Movie shortcuts Personal info ... Recommend this site Hausdorff Distance We talk about points in a space , like in the definition of a circle as a set of all points equidistant from a given point. But we have already pointed to an example of a distance defined between two functions . Functions can also be added and multiplied , and in mathematics sets whose elements are functions are called space s (sometimes, of course, functional spaces .) as many other sets . The advantage is in that, once some common properties of various sets have been isolated, their study will apply to all the particular cases regardless of the nature of elements the sets comprise. It may be confusing sometimes , for example, when we consider spaces of functions or curves or matrices. A point in a space is something elementary, simple and, like an atom (of many years ago), indivisible. But here exactly lies one of the sources from which mathematics draws its power. Going to a level of abstraction that knows nothing of the nature of the objects it deals with spreads the results over vast territory strewn with apparently unrelated objects pointing to unexpected similarities and, by doing so, outlines also the limits of analogy. We not only learn what is common but better understand the differences. Here I wish to consider spaces whose elements - points - are sets themselves.

Kurt Goedel proved the following results: Any fundamental axiomatic system (one that is sufficient to prove the arithmetic properties of the natural numbers) cannot be both consistent and complete. It is impossible to prove the consistency of a fundamental axiomatic system within itself. See also GoedelsTheoremDiscussion Consistency here means that it is not possible within the system to prove both a predicate and its negation. I.e. The system possesses NonContradiction Complete here means that all predicates are decidable (can be proved or disproved) within the system. Goedel's first result (known as the Completeness Theorem) states that something is true if and only if it is provable. Goedel's second result states that either an axiomatic system is inconsistent and possesses contradictions, or it is

Theorem: Completeness Theorem in R Let be a Cauchy sequence of real numbers. Then the sequence is bounded. Let be a sequence of real numbers. The sequence is Cauchy if and only if it converges to some limit a Proof: The proof of the first statement follows closely the proof of the corresponding result for convergent sequences. Can you do it ? To prove the second, more important statement, we have to prove two parts: First, assume that the sequence converges to some limit a . Take any . There exists an integer N such that if then j . Hence: j - a k j k if Thus, the sequence is Cauchy. Second, assume that the sequence is Cauchy (this direction is much harder). Define the set S R j for all j Since the sequence is bounded (by part one of the theorem), say by a constant M , we know that every term in the sequence is bigger than -M . Therefore -M is contained in S . Also, every term of the sequence is smaller than M , so that S is bounded by M . Hence, S is a non-empty, bounded subset of the real numbers, and by the least upper bound property it has a well-defined, unique least upper bound. Let a = sup( S We will now show that this a is indeed the limit of the sequence. Take any
