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…

Morita equivalences induced by bimodules over Hopf-Galois extensions

S. Caenepeel, S. Crivei, A. Marcus +1

Let $H$ be a Hopf algebra, and $A, B$ be $H$ -Galois extensions. We investigate the category $_{A} M_{B}^{H}$ of relative Hopf bimodules, and the Morita equivalences between $A$ …
