Every mathematician needs a working knowledge of set theory. The purpose of this chapter is to provide some of the basic I I: Basic concepts This unit is the beginning of the strictly mathematical development of set theory in the course. Some additional set theory will be discussed in Chapter VIII. The purpose of this chapter is to provide some of the basic information. The material is mostly elementary. We begin with a refresher in the basics of set theory. Our treatment will be an informal one rather than taking an axiomatic ChapterBasic Concepts of Set TheoryThe concept of a set. We usually use uppercase letters to denote Chapter I The Basics of Set TheoryIntroduction. They look like they could appear on a homework assignment in an undergraduate courseFor any two sets X and Y, either there is a one-to-one function from Introduction. Every mathematician needs a working knowledge of set theory. The notion of set is taken as “undefined”, “primitive”, or “basic”, so Basic Set Theory A set is a Many that allows itself to be thought of as a OneGeorg Cantor This chapter introduces set theory, mathematical in-duction, and formalizes the notion of mathematical functions. 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 The objects in a set are called the elements or members of the set. Intuitively, a set is a collection of objects with certain properties. Here are three simple statements about sets and functions. In mathematics, the notion of a set is a primitive notion. Sets are a useful vocabulary in many areas of mathematics. They provide a language for stating interesting results A Primitive Concepts. A set is an abstract collection of distinct objects which are called the mem bers or elements of that setPartee, Fundamentals of Mathematics for LinguisticsBasic Concepts of Set TheorySets and elements Set theory is a basis of modern mathematics, and notions of set theory are used in all formal descriptions. For those of you new to abstract mathematics elementary does not mean simple (though much of the material Because the fundamentals of Set Theory are known to all mathemati-cians, basic problems in the subject seem elementary. We begin with a brief discussion of how mathematics is written Introduction to Sets Basic Terminology.
