Souayah [10] introduced the concept of partial Sb-metric spaces. In this paper, we established a fixed point theorem for a new class of contractive mappings and a generalization of Theorem 2 from [T. Suzuki, A generalized Banach contraction principle that characterizes metric completeness, Proc. Am. Math. Soc. 136, (2008), 1861-1869] in partial Sb-metric spaces. We provide an example in support of our result.</p>2018-01-22T16:06:21+00:00##submission.copyrightStatement##http://m-sciences.com/index.php?journal=jast&page=article&op=view&path%5B%5D=1321On semi-compact and semi-Lindelof Quotient Radon measure manifolds and their intrinsic structures2018-06-19T19:17:38+00:00S.
