fuzzy set theory

In mathematics , a well-defined collection of definite objects is called a set. George Cantor is regarded as the "Father of Set theory". The concept of "Sets" is basic in all branches of mathematics . Important terms in Sets are:..

A well-defined collection of distinct objects is called a set..

In any application of the theory of sets, the members of all sets under consideration usually belong to some fixed large set called the universal set. Usually we denote the universal set by the letter..

If two sets are given, a set can be formed by using all the elements of the two sets. Such a collection is called the union of the given sets..

The Operations on Sets are: Union of sets, Intersection of sets, Disjoint sets, Difference of two sets (Relative complement), Symmetric Difference of two sets, Complement of a set..

Two finite sets A and B are said to be equivalent sets if cardinality of both sets are equal i.e. n (A) = n (B..

The number of elements in a finite set A, is the cardinality of A and is denoted by n(A..

The family of all subsets of any set S is called the power set of S. We denote the power set of S by P (S). If a set S is finite, say S has n elements, then the power set of S can be shown to have 2 n elemen..
