Let be a Markov kernel on a measurable space with countably generated -algebra, let :→[1, +∞[ such that ≤ with ≥0, and let be the space of measurable functions on satisfying ‖‖=sup{()|()|, ∈}<+∞. We prove that is quasi-compact on if and only if, for all , contains a subsequence converging in to=∑ () , where the ’s are non-negative bounded measurable functions on and the ’s...
