Topologies and approximation operators induced by binary relations
Nurettin Bagirmaz, A. Fatih Ozcan Hatice Tasbozan, Ilhan Icen
Rough set theory is an important mathematical tool for dealing with uncertain or vague information. This paper studies some new topologies induced by a binary relation on universe…
Coverings and Actions of Structured Lie Groupoids I
M. Habil Gürsoy, Ilhan Icen, A. Fatih Özcan
In this work we deal with coverings and actions of Lie group- groupoids being a sort of the structured Lie groupoids. Firstly, we define an action of a Lie group-groupoid on some L…
Holonomy and monodromy groupoids
Ronald Brown, Ilhan Icen, Osman Mucuk
We outline the construction of the holonomy groupoid of a locally Lie groupoid and the monodromy groupoid of a Lie groupoid. These specialise to the well known holonomy and monodro…
Sheaves and Local Subgroupoids
Ilhan Icen
This is an introduction to the notion of local subgroupoid introduced by the author and R. Brown. It can also serve as an introduction to an application of sheaf theory, and so cou…
Extendibility, monodromy and local triviality for topological groupoids
Osman Mucuk, Ilhan Icen
A groupoid is a small category in which each morphism has an inverse. A topological groupoid is a groupoid in which both sets of objects and morphisms have topologies such that all…
Some Results for the Local Subgroupoids
Ilhan Icen, Osman Mucuk
The notion of local subgroupoids as generalition of a local equivalence relations was defined by the first author and R.Brown. Here we investigate some relations between transitive…
