Introduction to Logic and Set Theory-2013-2014 General Course Notes December 2, 2013 These notes were prepared as an aid to the student. AzB x(x A l x B) { x [(x A x B) (x B x A)] The notion of set is taken as “undefined”, “primitive”, or “basic”, so we don’t try to define what a set is, but we can give an informal description, describe p. cm. Basic Set Theory LX 502 - Semantics I September 11, 2008 1. The set of even integers can be written: {2n : n is an integer} The opening and closing curly braces denote a set, 2n Cynthia Church pro-duced the first electronic copy in December 2002. Elements of Set Theory eleven; all oxygen molecules in the atmosphere; etc. Introduction to Set Theory James H. Steiger. Set Theory and Logic: Fundamental Concepts (Notes by Dr. J. Santos) A.1. Although this is not sufficiently well appreciated, it is difficult to give a general characterization of extensional definitions. The elements of a set are the objects in a set. A book of set theory / Charles C Pinter. These notes for a graduate course in set theory are on their way to be-coming a book. ± The empty set is denoted by or by { }. The second collection is called a multiset. A Set is any well defined collection of “objects.” Definition. The theory of sets is a vibrant, exciting math­ ematical theory, with its own basic notions, fundamental results and deep open problems, and with significant applications to other mathematical theories. James Talmage Adams “A revised and corrected republication of Set Theory, originally published in 1971 by Addison-Wesley Publishing Company, Reading, Massachusetts.” Summary: “This accessible approach to set theory for upper-level undergraduates poses rigorous but simple arguments. The technique of using the concept of a set to answer questions is hardly new. PDF. Sets are often specified with curly brace notation. These notes were prepared using notes from the course taught by Uri Avraham, Assaf Hasson, and of course, Matti Rubin. 1.1. That is, we admit, as a starting point, the existence of certain objects (which we call sets), which we won’t define, but which we assume satisfy some basic properties, which we express as axioms. Let xbe arbitrary. In mathematics, the notion of a set is a primitive notion. SET THEORY Empty Set The set that contains no element is called the empty set or null set . Primitive Concepts. 1.1 Sets Mathematicians over the last two centuries have been used to the idea of considering a collection of objects/numbers as a single entity. Primitive Concepts. Ling 310, adapted from UMass Ling 409, Partee lecture notes March 1, 2006 p. 4 Set Theory Basics.doc 1.4. ± Note: z { } A=B x(x A l x B) ± Two sets A, B are equal iff they have the same elements. Each In mathematics, the notion of a set is a primitive notion. An Introduction to Elementary Set Theory Guram Bezhanishvili and Eachan Landreth 1 Introduction In this project we will learn elementary set theory from the original historical sources by two key gures in the development of set theory, Georg Cantor (1845{1918) and Richard Dedekind (1831{1916). We start with the basic set theory. 2.1 Set Theory A set is a collection of distinct objects. 1. The elements of a set are the objects in a set. An(B[C) = (AnB) \(AnC) Proof. Usually we denote sets with upper-case letters, elements with lower-case letters. Sets and elements Set theory is a basis of modern mathematics, and notions of set theory are used in all formal descriptions. Usually we denote sets with upper-case letters, elements with lower-case letters. a staff with no notes on it Each line or space on the staff is for its own note. A Set is any well defined collection of “objects.” Definition. This chapter will be devoted to understanding set theory, relations, functions. Set Theory and Logic: Fundamental Concepts (Notes by Dr. J. Santos) A.1. Subsets A set A is a subset of a set B iff every element of A is also an element of B.Such a relation between sets is denoted by A ⊆ B.If A ⊆ B and A ≠ B we call A a proper subset of B and write A ⊂ B. Itis perhaps best to say that an extensional definition of a set is one that is givenbyanenumera-tion (listing) of all its elements.

They are not guaran-teed to be comprehensive of the material covered in the course. 110 CHAPTER 4. Notes represent sounds called pitches. This means that {1,2,3} is a set but {1,1,3} is not because 1 appears twice in the second collection. They originated as handwritten notes in a course at the University of Toronto given by Prof. William Weiss. Course Notes Page 1. Notation. Theorem 1.4. (Caution: sometimes ⊂ is used the way we are using ⊆.) Basic Concepts of Set Theory. What this book is about. The five horizontal lines on which the notes sit are called a staff. Sets Definition. The set theoretic di erence AnBis de ned by x2AnBi x2Aand x62B. Introduction. These entities are what are typically called sets. Because music employs a set of pitches (ranging from low to high), the staff acts like a map for the notes--allowing us to hear, read or write them as: Lower
