Baxter operators in Ruijsenaars hyperbolic system IV. Coupling constant reflection symmetry
N. Belousov, S. Derkachov, S. Kharchev +1
We introduce and study a new family of commuting Baxter operators in the Ruijsenaars hyperbolic system, different from that considered by us earlier. Using a degeneration of Rains…
