Classification of Non-Affine Non-Hecke Dynamical R-Matrices

A complete classification of non-affine dynamical quantum $R$-matrices obeying the $\mathcal{G}{l}_n(\mathbb{C})$-Gervais-Neveu-Felder equation is obtained without assuming either Hecke or weak Hecke conditions. More general dynamical dependences are observed. It is shown that any solution is built upon elementary blocks, which individually satisfy the weak Hecke condition. Each solution is in particular characterized by an arbitrary partition ${{\mathbb I}(i), i\in{1,…,n}}$ofthesetofindices${1,…,n}$intoclasses,${\mathbb I}(i)$beingtheclassoftheindex$i$, and an arbitrary family of signs $({ϵ}_{\mathbb{I}}{)}_{\mathbb{I}\in \mathbb{I}(i),i\in 1,\mathrm{.}\mathrm{.}\mathrm{.},n}$ on this partition. The weak Hecke-type $R$-matrices exhibit the analytical behaviour $R_{ij,ji}=f(\epsilon_{{\mathbb I}(i)}\Lambda_{{\mathbb I}(i)}-\epsilon_{{\mathbb I}(j)}\Lambda_{{\mathbb I}(j)})$,where$f$ is a particular trigonometric or rational function, $\Lambda_{{\mathbb I}(i)}=\sum\limits_{j\in{\mathbb I}(i)}\lambda_j$,and$(\lambda_i)_{i\in{1,…,n}}$ denotes the family of dynamical coordinates.
