2. INTRODUCTIONS
SETS
What is sets in mathematics? A set is a collection of distinct objects, considered as an
object in its own right. Sets are one of the most fundamental concepts in mathematics.
Developed at the end of the 19th century, set theory is now a ubiquitous part of mathematics,
and can be used as a foundation from which nearly all of mathematics can be derived. In
mathematics education, elementary topics such as Venn diagrams are taught at a young age,
while more advanced concepts are taught as part of a university degree.
SETS THEORY
Set theory is the branch of mathematics that studies sets, which are collections of
objects. Although any type of object can be collected into a set, set theory is applied most
often to objects that are relevant to mathematics. The language of set theory can be used in
the definitions of nearly all mathematical objects.
The modern study of set theory was initiated by Georg Cantor and Richard Dedekind
in the 1870s. After the discovery of paradoxes in naive set theory, numerous axiom systems
were proposed in the early twentieth century, of which the Zermelo–Fraenkel axioms, with
the axiom of choice, are the best-known.
Concepts of set theory are integrated throughout the mathematics curriculum in the
United States. Elementary facts about sets and set membership are often taught in primary
school, along with Venn diagrams, Euler diagrams, and elementary operations such as set
union and intersection. Slightly more advanced concepts such as cardinality are a standard
part of the undergraduate mathematics curriculum.
Set theory is commonly employed as a foundational system for mathematics,
particularly in the form of Zermelo–Fraenkel set theory with the axiom of choice. Beyond its
foundational role, set theory is a branch of mathematics in its own right, with an active
research community. Contemporary research into set theory includes a diverse collection of
topics, ranging from the structure of the real number line to the study of the consistency of
large cardinals.
3. SETS HISTORY
Mathematical topics typically emerge and evolve through interactions among many
researchers. Set theory, however, was founded by a single paper in 1874 by Georg Cantor:
"On a Characteristic Property of All Real Algebraic Numbers".[1][2]
Since the 5th century BC, beginning with Greek mathematician Zeno of Elea in the
West and early Indian mathematicians in the East, mathematicians had struggled with the
concept of infinity. Especially notable is the work of Bernard Bolzano in the first half of the
19th century. The modern understanding of infinity began in 1867-71, with Cantor's work on
number theory. An 1872 meeting between Cantor and Richard Dedekind influenced Cantor's
thinking and culminated in Cantor's 1874 paper.
Cantor's work initially polarized the mathematicians of his day. While Karl
Weierstrass and Dedekind supported Cantor, Leopold Kronecker, now seen as a founder of
mathematical constructivism, did not. Cantorian set theory eventually became widespread,
due to the utility of Cantorian concepts, such as one-to-one correspondence among sets, his
proof that there are more real numbers than integers, and the "infinity of infinities" ("Cantor's
paradise") the power set operation gives rise to.
The next wave of excitement in set theory came around 1900, when it was discovered
that Cantorian set theory gave rise to several contradictions, called antinomies or paradoxes.
Bertrand Russell and Ernst Zermelo independently found the simplest and best known
paradox, now called Russell's paradox and involving "the set of all sets that are not members
of themselves." This leads to a contradiction, since it must be a member of itself and not a
member of itself. In 1899 Cantor had himself posed the question: "what is the cardinal
number of the set of all sets?" and obtained a related paradox.
The momentum of set theory was such that debate on the paradoxes did not lead to its
abandonment. The work of Zermelo in 1908 and Abraham Fraenkel in 1922 resulted in the
canonical axiomatic set theory ZFC, which is thought to be free of paradoxes. The work of
analysts such as Henri Lebesgue demonstrated the great mathematical utility of set theory.
Axiomatic set theory has become woven into the very fabric of mathematics as we know it
today.
4. SETS DEFINITION
Georg Cantor, the founder of set theory, gave the following definition of a set at the
beginning of his Beiträge zur Begründung der transfiniten Mengenlehre.
A set is a gathering together into a whole of definite, distinct objects of our perception and of
our thought - which are called elements of the set.
The study of algebra and mathematics begins with understanding sets. A set is
something that contains objects. To be contained in a set, an object may be anything that you
want to consider. An object in a set may even be another set that contains its own objects. In
everyday language, a set can also be called a “collection” or “container”, but in mathematics,
the term set is preferred. The objects that a set contains are called its members.
The elements or members of a set can be anything: numbers, people, letters of the
alphabet, other sets, and so on. Sets are conventionally denoted with capital letters. Sets A
and B are equal if and only if they have precisely the same elements.
As discussed below, the definition given above turned out to be inadequate for formal
mathematics; instead, the notion of a "set" is taken as an undefined primitive in axiomatic set
theory, and its properties are defined by the Zermelo–Fraenkel axioms. The most basic
properties are that a set "has" elements, and that two sets are equal (one and the same) if and
only if they have the same elements.
CONCEPTS
A set A consists of distinct elements :
If such elements are characterized via a property E, this is symbolized as follows:
satisfies property E}.
5. The following notations are commonly used:

is not element / member of

If ( ), is called a finite (infinite) set.
Two sets are called equipotent, if there exists a bijective map between their elements (
for finite sets and ).
The set of all subsets of is called power set, i.e. . . In
particular, we have and . Moreover, .
The following sets are standardly denoted by the respective symbols:
natural numbers:
integers:
rational numbers:
real numbers:
complex numbers:
The following notations are also commonly used and as
as well as , ,,, ,, respectively.
6. OPERATIONS ON SETS
The following operations can be applied to sets and :
Union of the sets A and B, denoted A ∪ B, is the set of all objects that are a member of
A, or B, or both. The union of {1, 2, 3} and {2, 3, 4} is the set {1, 2, 3, 4}.
Intersection of the sets A and B, denoted A ∩ B, is the set of all objects that are
members of both A and B. The intersection of {1, 2, 3} and {2, 3, 4} is the set {2, 3} .
Set difference, complement of U and A, denoted U A is the set of all members of U
that are not members of A. The set difference {1,2,3} {2,3,4} is {1} , while,
conversely, the set difference {2,3,4} {1,2,3} is {4} . When A is a subset of U, the
set difference U A is also called the complement of A in U. In this case, if the choice
of U is clear from the context, the notation Ac is sometimes used instead of U A,
particularly if U is a universal set as in the study of Venn diagrams.
Symmetric difference of sets A and B is the set of all objects that are a member of
exactly one of A and B (elements which are in one of the sets, but not in both). For
instance, for the sets {1,2,3} and {2,3,4} , the symmetric difference set is {1,4} . It is
the set difference of the union and the intersection, (A ∪ B) (A ∩ B).
Cartesian product of A and B, denoted A × B, is the set whose members are all
possible ordered pairs (a,b) where a is a member of A and b is a member of B.
Power set of a set A is the set whose members are all possible subsets of A. For
example, the power set of {1, 2} is { {}, {1}, {2}, {1,2} } .
Some basic sets of central importance are the empty set (the unique set containing no
elements), the set of natural numbers, and the set of real numbers.
7. The so- called Venn diagrams illustrate the set operations.
