An example is given here to illustrate the usability of the obtained results.http://vonneumann-publishing.com/cna/106/download-fixed-points-of-multivalued-theta-contractions-on-closed-ballVon Neumann Publishing House Inc.Communications in Nonlinear Analysis(CNA)2371-79203200000000Common coupled fixed point theorem for two pairs of hybrid maps in complex valued metric spaces5267ENKonduru Pandu RangaRaoDepartment of Mathematics, Acharya Nagarjuna University, Nagarjuna Nagar -522 510, A.P., IndiaShaikSadikDepartment of Mathematics, Sir C R R College of Engineering, Eluru- 534 007, West Godhawari, A.P, IndiaSaurabhManroDepartment of Mathematics, Thapar University, Patiala, Punjab, IndiaIn this paper, we prove a common coupled fixed point theorem for two hybrid pairs of maps with greatest lower bound property in complex valued metric spaces.

Firstly, we establish a tripled coincidence fixed point theorem for a sequence of mappings involving Geraghty contraction using compatibility and weakly reciprocally continuous maps in the structure of partially ordered metric spaces. The technique used in A. Roldan et al. \cite{les24} and in S. Radenovic \cite{les25} are not applicable on the presented theorems, we show that our results can not be obtained from the existing results in this field of study and thus our results are completely new and give rise a new dimension. Secondly, the notable works due to V. Berinde \cite{les20}, V. Lakshmikantam and L. Ciric \cite{les8} and Babu and Subhashini \cite{les22} are generalized and extended. Finally, some sufficient conditions are given for the uniqueness of a tripled common fixed point. Consequently, we point out some slip-ups in the main results of R. Vats et al.\cite{les19} and present a furnished version of the same. Some illustrative examples to highlight the realized improvements are also furnished. Moreover, existence and uniqueness for the solution of an initial-boundary-value problem is discussed. On the other hand, as an application to establish existence and uniqueness for the system of integral equations our results are utilized.http://vonneumann-publishing.com/cna/114/download-some-remarks-on-tripled-fixed-point-theorems-for-a-sequence-of-mappings-satisfying-geraghty-contraction-with-applicationsVon Neumann Publishing House Inc.Communications in Nonlinear Analysis(CNA)2371-79203220171213Note on some Iyengar integral inequalities8790ENKhaledBoukerriouaLanos Laboratatory , University of Badji-Mokhtar, Annaba, AlgeriaBadreddineMeftahLaboratoire des Télécommunications, Faculté des Sciences et de la Technologie, Université 8 Mai 1945 de Guelma,.
