In this talk, after reviewing the concept of covering and semicovering maps, first we give a

modified definition for semicovering maps which seems simpler than the original one given by

J. Brazas. Second we present some conditions...

In this paper, by reviewing the concept of semicovering maps, we present some conditions under which a local homeomorphism becomes a semicovering map. We also obtain some conditions under which a local homeomorphism is a covering map....

In this paper, by reviewing the concept of subcovering and semicovering maps, we extend the

notion of subcovering map to subsemicovering map. We present necessary and sufficient condition

for a local homeomorphism to be a subsemicovering...

In this talk we are interested to focus on subgroups of topologized fundamental groups and some relationships between generalized covering subgroups and some famous subgroups of the fundamental group equipped with the ...

with respect to H, strong H-SLT space, we investigate the existence of a covering map for strong H-SLT spaces. Moreover, we show that a semicovering map is a covering map in the presence of strong H-SLT property. Among other things, we present conditions under...

In this paper, by reviewing the concept of subcovering and semicovering maps, we extend the notion of subcovering map to subsemicovering map. We present some necessary or sufficient conditions for a local homeomorphism to be a subsemicovering map...

the fundamental group equipped with the

compact-open topology or the Whisker topology. Moreover, we present some conditions

under which generalized coverings, semicoverings and coverings are equal....

Let $H$ be a subgroup of $\\pi_{1}(X,x_{0})$. In this paper, we extend the concept of $X$ being SLT space to $H$-SLT space at $x_0$. First, we show that the fibers of the endpoint projection $p_{H}:\\widetilde {X}_{H}\\rightarrow ...
