Box 1664 Al Khobar, KINGDOM OF SAUDI ARABIAIn 2017 S. Ghour and B. Irshedat defined the θω - closure operator as a new topological operator and introduced θω - open sets as a new class of sets and proved that this class of sets is strictly between the class of open sets and the class of θ - open sets. In this paper we introduce θω - continuous, θω - irresolute, θω - open, θω - closed, pre - θω - open, θω - pre closed, contra θω - continuous and almost contra θω - continuous mappings and investigate properties and characterizations of these new types of mappings in topological spaces.472020472020186207https://www.wseas.org/multimedia/journals/mathematics/2020/a365106-056.pdf10.37394/23206.2020.19.18http://www.wseas.org/multimedia/journals/mathematics/2020/a365106-056.pdf10.2298/fil1716369aSamer Al-Ghour, Bayan Irshedat, The Topology of Θω-open Sets, Filomat (Faculty of Sciencees and Mathematics, University of Nis, Serbia) 31:16 (2017), 5369 – 5377. 10.5269/bspm.v32i2.20059H.H.
