Study Notes
What is a Set?
- A set is a mathematical model for a collection of different things.
- A set can contain elements or members of any kind, including numbers, symbols, points in space, lines, geometrical shapes, variables, or even other sets.
Types of Sets
- The empty set is a set with no elements.
- A singleton is a set with a single element.
- A set can have a finite number of elements or be an infinite set.
Properties of Sets
- Two sets are equal if they have precisely the same elements.
- This property is called extensionality.
- As a result, there is only one empty set.
Importance of Sets
- Sets are ubiquitous in modern mathematics.
- Set theory, specifically Zermelo–Fraenkel set theory, has been the standard way to provide rigorous foundations for all branches of mathematics since the 20th century.
Notation
- Sets are commonly denoted by capital letters in italic in mathematical texts.
