Solution Math 17 Chapter 1 1 Sets Set Operations And Number Sets Given sets a and b, we have the following definitions: 1. the union of a and b is the set a [ b = fx j x 2 a or x 2 bg: 2. the intersection of a and b is the set a \ b = fx j x 2 a and x 2 bg: 3. the set difference of a and b is the set a n b = fx 2 a j x =2 bg: 4. the complement of a is the set ac = fx j x =2 ag. Lecture 1: sets, set operations, and mathematical induction (tex) sets and their operations (union, intersection, complement, demorgan’s laws), the well ordering principle of the natural numbers, the theorem of mathematical induction and applications. lecture 2: cantor’s theory of cardinality (size) (pdf). 1 lecture 1 { elements of set theory and mathematical induction 1.1 elements of set theory the notion of a set is one of the most important initial and nonde nable notions of the modern mathematics. by a \set" we will understand any collection into a whole mof de nite and separate objects mof our intuition or our thought (georg cantor). Chapter 1 sets and notation 1.1 defining sets definition. a set is an unordered collection of distinct objects. the objects in a set are called the elements, or members, of the set. a set is said to contain its elements. a set can be defined by simply listing its members inside curly braces. for example,.

Although the facts that ∅ ⊆ b and b ⊆ b may not seem very important, we will use these facts later, and hence we summarize them in theorem 5.1. theorem 5.1. for any set b, ∅ ⊆ b and b ⊆ b. in section 2.3, we also defined two sets to be equal when they have precisely the same elements. Prime number. for instance, 2 is a prime number.induction step: let n 2 z , and assume that p(n) holds, i.e., that th. re are at least n prime numbers p1 < : : : < pn. we need to show that p(n 1) holds, i.e., there is at least one prime number. di erent from the numbers we have alread. lish this, consider the.
