... Injections, Surjections and Bijections • Let f be a function from A to B. • Definition: f is one-to-one (denoted 1-1) or injective if preimages are unique. Note: this means that if a b then f(a) f(b). • Definition: f is onto or surjective if every y in B has a preimage. Note: this means that fo ...

... Definition 7.1.1. Given sets A and B, a binary relation R W A ! B from1 A to B is a subset of A B. The sets A and B are called the domain and codomain of R, respectively. We commonly use the notation aRb or a R b to denote that .a; b/ 2 R. A relation is similar to a function. In fact, every funct ...

Section 1.1 Introduction to Sets Set: A set is a collection of objects
... More Notation: The symbol ∈ stands for the word element. An object is an element of a set if it is a list of all of the elements of a particular set. 5 ∈ A means “5 is an element of the set A.” When you see the notation 5 ∈ A, it means that 5 will be in the list if you make a list of all of the elem ...
