Complex rational Ruijsenaars model. The two-particle case

N. M. Belousov, G. A. Sarkissian, V. P. Spiridonov

We consider a complex rational degeneration of the hyperbolic Ruijsenaars model emerging in the limit $ω_{1} + ω_{2} \to 0$ (or $b \to $ in $2 d$ CFT) and investigate in detail the tw…

Complex binomial theorem and pentagon identities

N. M. Belousov, G. A. Sarkissian, V. P. Spiridonov

We consider different pentagon identities realized by the hyperbolic hypergeometric functions and investigate their degenerations to the level of complex hypergeometric functions.…
