Abstract
GHOUR, Samer Al; MANSUR, Kafa and SALCEDO-REYES, Juan Carlos. Between Open Sets and Semi-Open Sets. Univ. Sci. [online]. 2018, vol.23, n.1, pp.9-20. ISSN 0122-7483. https://doi.org/10.11144/javeriana.sc23-1.bosa.
We introduce and investigate ω s-open sets as a new class of sets which lies strictly between open sets and semi-open sets. Then we use ω s-open sets to introduce ω s-continuous functions as a new class of functions between continuous functions and semi-continuous functions. We give several results and examples regarding our new concepts. In particular, we obtain some characterizations of ω s-continuous functions.
Keywords : Semi-open set; ω-open set; Semi-continuous function.
