The next proposition, which is the basis of the proof of the main theorem of this paper, was proved originally by Darbo (1). Proposition 2.5. (The fixed point theorem for k-set contractions (A:<1)).

Darbo's fixed point theorem [10] which ensures the existence of fixed point is an essential application of this measure, since it extends both Schauder fixed point and Banach contraction principle.

$\begingroup$ I think Bessaga's result is interesting in that it suggest that, in order to solve a fixed point problem T(x)=x, where unicity is suspected (together with unicity of periodic points), then one should rather look for a convenient distance that makes T a contraction, instead of creating another variant of the Banach contraction theorem (Btw, there are thousands of generalizations. subset of a Banach algebra X:A useful prototype for solving equations of the type (1) is the celebrated ﬁxed point theorem due to Dhage [15], see also for example [3, 6, 7, 16, 25] and the references therein, it stated that A B + C has at least one ﬁxed point in S;when A;B and C fulﬁll: B is completely continuous, A an Banach's fixed point theorem for contraction maps has been widely used to analyze the convergence of iterative methods in non-convex problems.

We explore how generally we can apply Banach's fixed point theorem to. However, the Polish mathematician Stefan Banach is credited with placing the underlying ideas into an abstract framework suitable for broad applications well beyond the scope of elementary differential and integral equations.
