%0 Journal Article %T On crossed modules in modified categories of interest %A Arslan %A Ahmet Faruk %A C£¿tin %A Selim %A Uslu %A Enver £¿nder %J - %D 2017 %X Sa£¿etak We introduce some algebraic structures such as singularity, commutators and central extension in modified categories of interest. Additionally, we introduce the cat^{1} -objects and internal categories with their connection to crossed modules in these categories, which gives rise to unification of many notions about (pre)crossed modules in various algebras of categories %K center %K central extension %K commutator %K singularity %U https://hrcak.srce.hr/index.php?show=clanak&id_clanak_jezik=260516
