Our results extend and generalize the results of Babu and Leta to a pair of maps in S-metric spaces and also generalize the result of Sedghi, Shobe, and Aliouche. We provide examples in support of our results.http://www.cna-journal.com/article_93094_50adab4d6d3b223cc5b9ddd31e19098b.pdfVonneumann Publishing House Ink CanadaCommunications in Nonlinear Analysis2371-79207120191001Fixed Point Results for Multivalued Operator in G-metric Space364992588ENSaurabh ManroTejwant SinghDepartment of Mathematics, Desh Bhagat University, Mandi Gobindgarh, Punjab, IndiaANIMESH GuptaDepartment of Mathematics, Sagar Institute of Engineering, Technology and Research, Ratibad Bhopal (M.P.), IndiaRajveer KaurDepartment of Mathematics, Desh Bhagat University, IndiaJournal Article20190715In this paper, we shall give some results on xed points of multivalued operator on Gmetric spaces by using the method of Kikkawa [6].

The purpose of this paper is to prove the existence of a global solution. Our technique is based on a suitable Lyapunov functional.http://www.cna-journal.com/article_95603_a35cbd670f2da34775bd7022f8128329.pdfVonneumann Publishing House Ink CanadaCommunications in Nonlinear Analysis2371-79207120191001Fixed point theorems on a quaternion-valued G-metric spaces738193096ENAdewale KayodeDepartment of Mathematics, University of Lagos, Nigeria.Johnson OlaleruDepartment of Mathematics, University of Lagos, Nigeria.Hudson AkeweDepartment of Mathematics, University of Lagos, Nigeria.Journal Article20190818In this paper, we introduce the concept of a quaternion-valued $G$-metric spaces which generalize real-valued $G$-metric spaces, complex-valued $G$-metric spaces, real-valued metric spaces and complex-valued metric spaces known in the literature.
