• A semi-abelian extension of a theorem by Takeuchi (2018, background): “10 we know that HopfK,coc is semi-abelian, and this implies that the category Grpd(HopfK,coc) of internal groupoids in HopfK,coc is itself semi-abelian (see [20], and Lemma 4.”
• Central extensions in semi-abelian categories (2002, background): “Since any protomodular category is Maltsev; the regular epimorphisms in Eq(C) are the levelwise regular epimorphisms [14].”
