Abstract
The theory of xed point is concerned with the conditions which guarantee that the operator
T : X ! X of a topological space X onto itself admits one or more xed points, that is,
point x 2 X for which x = T(x). This theory began in 1912 with the work of Brouwer, who
proved that any continuous self-mapping of a closed unit ball of n-dimensional Euclidean
space has at least one xed point. The other fundamental result of Brouwer;s xed point
theorem was given by Banach in 1922 which is popularly known as a Banach Contraction
Principle or contraction mapping theorem of Banach.
