Tilting pairs and Wakamatsu tilting pairs of subcategories over cleft extensions
Guoqiang Zhao, Juxiang Sun
Let be a cleft extension of abelian categories. We prove that the functor preserves and reflects (Wakamatsu) tilting pairs of subcategories…
Silting and tilting objects in cleft extensions of abelian categories
Guoqiang Zhao, Juxiang Sun
We establish connections between silting and tilting objects in an abelian category and those in a cleft extension of , which provides a me…
Constructions of symmetric separable equivalences and their applications
Juxiang Sun, Guoqiang Zhao
Let and be symmetrically separably equivalent Artin algebras. We prove that there exist symmetrical separable equivalences between certain endomorphism algebras of modules.…
Gorenstein categories and separable equivalences
Guoqiang Zhao, Juxiang Sun
Let be an additive subcategory of left -modules, we establish relations of the orthogonal classes of and (co)res under sepa…
-left approximation dimensions under Stable equivalence
Juxiang Sun, Guoqiang Zhao, Junling Zheng
In this paper, we investigate some transfer properties of -left approximation dimensions of modules of stably equivalent Artin algebras having neither nodes nor semisimple direc…
