Equivalence of the categories of categorical groups and cssc-crossed modules

Tamar Datuashvili, Osman Mucuk, Nazmiye Alemdar +1

In [8] we proved that any categorical group defines a c-crossed module, which is a cssc-crossed module defined in the same paper. In [9] we constructed a categorical group for any…

From cssc-crossed modules to categorical groups

Tamar Datuashvili, Osman Mucuk, Nazmiye Alemdar +1

For any cssc-crossed module a category is constructed, equipped with a structure and proved that this is a coherent categorical group. Together with a result of the previous paper,…

Coverings and liftings of generalized crossed modules

Gamze Aytekin Arici, Tunçar Şahan

In the theory of crossed modules, considering arbitrary self-actions instead of conjugation allows for the extension of the concept of crossed modules and thus the notion of genera…

Categories internal to crossed modules

Tunçar Şahan, Jihad Jamil Mohammed

In this study, internal categories in the category of the crossed modules are characterized and it has been shown that there is a natural equivalence between the category of the cr…

Derived crossed modules

Tunçar Şahan

In this study, we interpret the notion of homotopy of morphisms in the category of crossed modules in a category of groups with operations using the categorical equiva…

Actor of categories internal to groups

Tunçar Şahan

In this study, using the Brown-Spencer theorem and in the ligth of the works of Norrie, in the category of internal categories within groups, also called group-groupoids, we interp…
