We introduce the notion of multivalued θ-contractions on the closed ball and we obtain some new fixed point<br />results for such contractions. An example is given here to illustrate the usability of the obtained results.

Some remarks on tripled ﬁxed point theorems for a sequence of mappings satisfying Geraghty contraction with applications

The purpose of this paper is threefold. Firstly, we establish a tripled coincidence fixed point theorem for a sequence of mappings involving Geraghty contraction using compatibility and weakly reciprocally continuous<br />maps in the structure of partially ordered metric spaces. The technique used in A. Roldan et al. [9] and<br />in S. Radenovic [10] are not applicable to the presented theorems, we show that our results cannot be<br />obtained from the existing results in this eld of study and thus our results are completely new and give rise to<br />a new dimension. Secondly, the notable works due to V. Berinde [3], V. Lakshmikantam and L. Ciric [8] and<br />Babu and Subhashini [1] are generalized and extended. Finally, some sufficient conditions are given for the<br />uniqueness of a tripled common fixed point. Consequently, we point out some slip-ups in the main results<br />of R. Vats et al.[12] and present a furnished version of the same. Some illustrative examples to highlight<br />the realized improvements are also furnished. Moreover, existence and uniqueness for the solution of an<br />initial-boundary-value problem are discussed. On the other hand, as an application to establish existence and<br />uniqueness for the system of integral equations our results are utilized.
