Factorization of Conditional Expectations on Kac Algebras and Quantum Double Coset Hypergroups

Kalyuzhnyi, A.A.; Chapovsky, Yu.A. (Український математичний журнал, 2003)

We prove that a conditional expectation on a Kac algebra, under certain conditions, decomposes into a composition of two conditional expectations of a special type and gives rise to a compact quantum hypergroup connected ...
On the group of extensions for the bicrossed product construction for a locally compact group

Chapovsky, Yu.A.; Kalyuzhnyi, A.A.; Podkolzin, G.B. (Algebra and Discrete Mathematics, 2004)

For the cocycle bicrossed product construction applied to a locally compact group and its two subgroups, we give a simple description of the group of the corresponding extensions in terms of the second cohomology group ...
