  • NON-EFFECTIVE ORBIFOLDS AND DOUBLE CATEGORIES 

    Sibih, Alanod (2017-08-31)
    Satake introduced Orbifolds in terms of an underlying space with an atlas of charts consisting of an open subset of Euclidean space with an action of a finite group. The representation of orbifolds by topological groupoids ...
  • Orbifold Atlas Groupoids 

    Sibih, Alanod (2013-04-05)
    We study orbifolds and strong maps of orbifolds. We begin with introducing a representation for orbifolds that consists of internal categories in the category of topological spaces. These categories are built from atlas ...
