  • Nicolai Reshetikhin


The main result of this note is the proof of degenerate quantum integrability of quantum spin Calogero–Moser systems and the description of the spectrum of quantum Hamiltonians in terms of the decomposition of tensor products of irreducible representations of corresponding Lie algebra.
