Relatively divisible and relatively flat objects in exact categories: Applications
Septimiu Crivei, Derya Keskin Tütüncü
We continue our study of relatively divisible and relatively flat objects in exact categories in the sense of Quillen with several applications to exact structures on finitely acce…
Essential and retractable Galois connections
Septimiu Crivei
For bounded lattices, we introduce certain Galois connections, called (cyclically) essential, retractable and UC Galois connections, which behave well with respect to concepts of m…
Correspondences of coclosed submodules
Septimiu Crivei, Hatice Inankıl, M. Tamer Koşan +1
We establish an order-preserving bijective correspondence between the sets of coclosed elements of some bounded lattices related by suitable Galois connections. As an application,…
Morita equivalences induced by bimodules over Hopf-Galois extensions
S. Caenepeel, S. Crivei, A. Marcus +1
Let be a Hopf algebra, and be -Galois extensions. We investigate the category of relative Hopf bimodules, and the Morita equivalences between …
