Abstract:
For the integrable discrete self-trapping chain, we construct Baxter Q-operators as the traces of the monodromy of certain M-operators that act in the quantum and auxiliary spaces. With this procedure, we obtain two basic M-operators and derive some functional relations between them such as intertwining relations and Wronskian-type relations between two basic Q-operators.
