    On Semicovering Maps 

    Type: Conference Paper
    Author : مجید کوکبی; بهروز مشایخی فرد; حمید ترابی اردکانی; majid kowkabi; Behrooz Mashayekhy Fard; Hamid Torabi Ardakani
    Year: 2015
    Abstract:

    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...

    ?When is a Local Homeomorphism a Semicovering Map 

    Type: Journal Paper
    Author : مجید کوکبی; بهروز مشایخی فرد; حمید ترابی اردکانی; majid kowkabi; Behrooz Mashayekhy Fard; Hamid Torabi Ardakani
    Year: 2017
    Abstract:

    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....

    On Subsemicovering 

    Type: Conference Paper
    Author : حمید ترابی اردکانی; مجید کوکبی; بهروز مشایخی فرد; Hamid Torabi Ardakani; majid kowkabi; Behrooz Mashayekhy Fard
    Year: 2016
    Abstract:

    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...

    On Relationship Between Generalized Covering Subgroups of Fundamental Groups 

    Type: Conference Paper
    Author : مهدی عبدالهی رشید; سیدزینال پاشایی; بهروز مشایخی فرد; حمید ترابی اردکانی; Mehdi Abdullahi Rashid; seyed zeynal pashaei; Behrooz Mashayekhy Fard; Hamid Torabi Ardakani
    Year: 2015
    Abstract:

    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 ...

    On strong small loop transfer spaces relative to subgroups of fundamental groups 

    Type: Journal Paper
    Author : سیدزینال پاشایی; بهروز مشایخی فرد; حمید ترابی اردکانی; مهدی عبدالهی رشید; seyed zeynal pashaei; Behrooz Mashayekhy Fard; Hamid Torabi Ardakani; Mehdi Abdullahi Rashid
    Year: 2019
    Abstract:

    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...

    ON SEMICOVERING, SUBSEMICOVERING, AND SUBCOVERING MAPS 

    Type: Journal Paper
    Author : مجید کوکبی; بهروز مشایخی فرد; حمید ترابی اردکانی; majid kowkabi; Behrooz Mashayekhy Fard; Hamid Torabi Ardakani
    Year: 2020
    Abstract:

    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...

    On Open Subgroups of Topologized Fundamental Group 

    Type: Conference Paper
    Author : سیدزینال پاشایی; مهدی عبدالهی رشید; بهروز مشایخی فرد; حمید ترابی اردکانی; seyed zeynal pashaei; Mehdi Abdullahi Rashid; Behrooz Mashayekhy Fard; Hamid Torabi Ardakani
    Year: 2015
    Abstract:

    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....

    Small Loop Transfer Spaces with Respect to Subgroups of Fundamental Groups 

    Type: Journal Paper
    Author : سیدزینال پاشایی; بهروز مشایخی فرد; حمید ترابی اردکانی; مهدی عبدالهی رشید; seyed zeynal pashaei; Behrooz Mashayekhy Fard; Hamid Torabi Ardakani; Mehdi Abdullahi Rashid
    Year: 2017
    Abstract:

    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 ...
