On some mappings in topological spaces

Journal Name:

Publication Year:

AMS Codes:

Abstract (2. Language): 
In this paper, we continue studying the properties of -semi-continuous and -semi-open functions introduced in [5], [10]. We also introduce -irresolute functions and -pre-semi-open (closed) functions and discuss their properties.
