QUASI b−OPEN AND STRONGLY b−OPEN FUNCTIONS

In this paper we introduce b− open, b− closed, quasi b− open, quasi b − closed, strongly b − open and strongly b − closed functions and investigate properties and characterizations of these new types of functions.

On Baer type criterion for $C$-dense‎, ‎$C$-closed and quasi injectivity

‎For the subclasses $mathcal{M}_1$ and $mathcal{M}_2$ of‎ ‎monomorphisms in a concrete category $mathcal{C}$‎, ‎if $mathcal‎{M}_2subseteq mathcal{M}_1$‎, ‎then $mathcal{M}_1$-injectivity‎ ‎implies $mathcal{M}_2$-injectivity‎. ‎The Baer type criterion is about‎ ‎the converse of this fact‎. ‎In this paper‎, ‎we apply injectivity to the classes of $C$-dense‎, ‎$C$-closed‎ ‎monomorphisms‎. ‎The con...

Quasi-convex Functions and Quasi-monotone Operators

The notions of a quasi-monotone operator and of a cyclically quasi-monotone operator are introduced, and relations between such operators and quasi-convex functions are established.
