Introduction To Set Theory Pdf Empty Set Infinity The document discusses different types of sets including finite sets, infinite sets, numerical sets, and the empty or null set. it provides examples of each type of set and explains key set concepts such as subsets, equality of sets, and order cardinality of sets. It is written for stu dents with a little background in logic, and some high school mathematics. it aims to scratch the tip of the surface of the phi losophy of set theory. by the end of this book, students reading it might have a sense of: how one might try to justify the axioms of zfc.
Set Theory Pdf One such way to axiomatize set theory and directly talk about classes is von neumann bernays g odel set theory. in this axiomatization, all the objects of study are classes. Set theory is foundational to modern mathematics, deeply involved with concepts of infinity and the axioms that govern mathematical structure. The empty set has no elements, so its cardinality is zero. for s any set, we write |s| to mean its cardinality. although |n| = ∞, we know |{n}| = 1. the set {n} is a set containing one element. that element is itself a set, containing infinitely many elements. In naïve set theory, sets are introduced and understood using what is taken to be the self evident concept of sets as collections of objects considered as a whole.

In our first lecture together, we'll discuss the big questions we will answer in cs103, then explore the finite and the infinite through the world of set theory. In set theory, the existence of finite sets is taken for granted, so long as the set is not defined inconsistently. there is the axiom in set theory that infinite sets exist. Around the start of the 20th century, zermelo and (later) fraenkel developed a version of set theory which avoids russell’s paradox and similar paradoxes. this zermelo fraenkel set theory is the subject of this course.
