Centralizers and Inverses to Induction as Equivalence of Categories

Lars Kadison

Given a ring homomorphism $B \to A$ , consider its centralizer $R = A^{B}$ , bimodule endomorphism ring $S = \End {}_BA_B$ and sub-tensor-square ring $T = (A ø_{B} A)^{B}$ . Nonassociative…

A note on Galois theory for bialgebroids

Lars Kadison

In this note we reduce certain proofs in \cite{KS, Karl, AMA} to depth two quasibases from one side only. This minimalistic approach leads to a characterization of Galois extension…

Depth Two and the Galois Coring

Lars Kadison

We study the cyclic module $_{S} R$ for a ring extension $A ∥ B$ with centralizer $R$ and bimodule endomorphism ring $S = E n d_{B} A_{B}$ . We show that if $A ∥ B$ is an H-separable H…
