Abstract

In this paper we give the denitions of t-lower level set (Lt(A)) and t-upper level

set (Ut(A)) of an Intuitionistic fuzzy set.[1] A t-lower level set is dened by giving a

lower boundry on A(x) + A(x): A t-upper level set is dened by giving an upper

boundry on A(x) + A(x): If A is an Intuitionistic fuzzy set of X then Lt(A) and

Ut(A) are subsets of X.

In this paper we give some theorems by using t-lower level sets and t-upper level

sets and prove them.
