| contents | In 2001--2013 Derkachov and Manashov with coauthors obtained simple and natural expressions of $R$-matrices for the principal series of representations of the groups $\mathrm{SL}(2,\mathbb{C})$, $\mathrm{SL}(2,\mathbb{R})$, $\mathrm{SL}(n,\mathbb{C})$, $\mathrm{SO}(1,n)$. The Yang--Baxter identities for these intertwining operators are kinds of multivariate hypergeometric transformations. Derivations of the identities are based on calculations 'of physical level of rigor' with divergent integrals. Our purpose is a formal mathematical justification of these results. |
