Comment on star-star relations in statistical mechanics and elliptic
gamma-function identities    [PDF]

Vladimir V. Bazhanov, Andrew P. Kels, Sergey M. Sergeev

We prove a recently conjectured star-star relation, which plays the role of an integrability condition for a class of 2D Ising-type models with multicomponent continuous spin variables. Namely, we reduce this relation to an identity for elliptic gamma functions, previously obtained by Rains.
