For the noncompact open SL(2, ℂ) spin chain, the eigenfunctions of the special matrix element of the monodromy matrix are constructed. The key ingredients of the whole construction are local Yang-Baxter -operators, -operator, and raising operators obtained by reduction from the -operator. The calcul...
