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

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 to a quantum Gelfand pair.
