Then ffag;fa;bgg= ffag;fa;agg= ffag;fagg= ffagg Since ffagg= ffcg;fc;dggwe must have fag= fcgand fag= fc;dg. Fido Sue Fred Aristotle Bob The collection of things in the world that are mortal The collection of things in the world that are men. 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 important properties of sets, and give examples. Selecting the material for presentation in this book often came down to deciding how much detail should be provided when explaining concepts and what constitutes a reasonable logical gap which can be independently ﬁlled in by the reader. Because the foundations of mathematics is relevant to philosophy. Set theory is the branch of mathematical logic that studies sets, which informally are collections of objects. In the first edition of this book, “studies in logic and the foundations of mathematics,” the set theory is discussed in its original form. The semantics of Predicate Logic is defined in terms of Set Theory. There are three reasons one might want to read about this: 1. It is written for the upper level undergraduate or beginning graduate students to help them prepare for advanced study in set theory and mathematical logic as well as other areas of mathematics, such as analysis, topology, and algebra. It has been and is likely to continue to be a a source of fundamental ideas in Computer Science from theory to practice; Computer Science, being a science of the arti cial, has had many of its constructs and ideas inspired by Set Theory. Introduction to Logic and Set Theory-2013-2014 General Course Notes December 2, 2013 These notes were prepared as an aid to the student. Set theory is a basis of modern mathematics, and notions of set theory are used in all formal descriptions. It only remains to de ne ha;biin terms of set theory. De nition 1.7 (Ordered Pair). (Sentence 1 tells us they are among the things that are mortal.) 3. It is also deals with Quine's systems. An Introduction To Set Theory. 1. Clearly if a= cand b= dthen ha;bi= ffag;fa;bgg= ffcg;fc;dgg= hc;di 1. 2 2. Suppose a= b. They are not guaran-teed to be comprehensive of the material covered in the course. This book describes some basic ideas in set theory, model theory, proof theory, and recursion theory; these are all parts of what is called mathematical logic. For its applications in topology, analysis, algebra, AI, databases. As an introduction to logic. ha;bi= ffag;fa;bgg Theorem 1.5. ha;bi= hc;dii a= cand b= d. Proof. A set theory textbook can cover a vast amount of material depending on the mathematical background of the readers it was designed for. 2. Set Theory is indivisible from Logic where Computer Science has its roots. This book provides an introduction to axiomatic set theory and descriptive set theory. These notes were prepared using notes from the course taught by Uri Avraham, Assaf Hasson, and of course, Matti Rubin. So a= c= d, in particular, a= cand b= d. 2.
