    • Group-2-groupoids and 2G-crossed modules 

      In this paper, we introduce the notion of a group-2-groupoid as a group object in the category of 2-groupoids. We also obtain a 2G-crossed module by using the structure of a group-2-groupoid. Then we prove that the category ...
    • Some notes on crossed semimodules 

      Temel, Sedat (Scientific Technical Research Council Turkey, TÜBİTAK, 2022)
      In this paper, we introduce the notion of lifting via a homomorphism of monoids for a crossed semimodule and give some properties. Further, we characterize actions and coverings of Schreier internal categories in the ...
