Centralizers and Inverses to Induction as Equivalence of Categories
Lars Kadison
Given a ring homomorphism , consider its centralizer , bimodule endomorphism ring $S = \End {}_BA_B$ and sub-tensor-square ring . 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 for a ring extension with centralizer and bimodule endomorphism ring . We show that if is an H-separable H…
On coseparable and biseparable corings
Tomasz Brzezinski, Lars Kadison, Robert Wisbauer
A relationship between coseparable corings and separable non-unital rings is established. In particular it is shown that an A-coring C has an associative A-balanced product. A Mori…
Dual Bialgebroids for Depth Two Ring Extensions
L. Kadison, K. Szlachanyi
We introduce a general notion of depth two for ring homomorphism N --> M, and derive Morita equivalence of the step one and three centralizers, R = C_M(N) and C = End_{N-M}(M ø_N M…
Hopf algebra actions on strongly separable extensions of depth two
Lars Kadison, Dmitri Nikshych
We bring together ideas in analysis of Hopf *-algebra actions on II_1 subfactors of finite Jones index and algebraic characterizations of Frobenius, Galois and cleft Hopf extension…
