Extended suprametric spaces and Stone-type theorem
Sumati Kumari Panda, Ravi P. Agarwal, Erdal Karapınar
Abstract
<abstract><p>Extended suprametric spaces are defined, and the contraction principle is established using elementary properties of the greatest lower bound instead of the usual iteration procedure. Thereafter, some topological results and the Stone-type theorem are derived in terms of suprametric spaces. Also, we have shown that every suprametric space is metrizable. Further, we prove the existence of a solution of Ito-Doob type stochastic integral equations using our main fixed point theorem in extended suprametric spaces.</p></abstract>
