We study a symmetric Markov extension of k-algebras N โ M, a certain kind of Frobenius extension with conditional expectation that is tracial on the centralizer and dual bases with a separability property. We place a depth two condition on this extension, which is essentially the requirement that th

For H an infinite dimensional co-Frobenius Hopf algebra over a field k, and A an H-comodule algebra, the smash product Aเ ปH \* r at is linked to the ring of coinvariants A c o H by a Morita context. We use the Morita setting to show that for co-Frobenius H, equivalent conditions for ArA c o H to be G
2 ร 2 . If H is abelian of order 8, we may use K = k H \* , and if H is abelian of order 4 we use K = kD 8 \* . If H โผ = D 8 , then in the two possible examples, one has K = kD 8 \* and the other has K = kQ 8 \* . If H โผ = 2 ร 2 ร 2 then H has two simple degree 2 characters, ฯ 1 and ฯ 2 , and they
We present a general construction producing pointed co-Frobenius Hopf algebras and give some classification results for the examples obtained.
We develop a new approach to the measure extension problem, based on nonstandard analysis. The class of thick topological spaces, which includes all locally compact and all K-analytic spaces, is introduced in this paper, and measure extension results of the following type are obtained: If (X, T) is
We bring together ideas in analysis on Hopf f-algebra actions on II 1 subfactors of finite Jones index [9,24] and algebraic characterizations of Frobenius, Galois and cleft Hopf extensions [3,13,14] to prove a non-commutative algebraic analogue of the classical theorem: a finite degree field extensi
