Let ${\bf g}$ be one of the twisted affine Lie algebra types $A_{2n}^{(2)}$ or $A_{2n-1}^{(2)}$, or let the type be $G_2^{(1)}$. Let ${\cal R}(\lambda)$ denote the universal dynami…

Let $cmathfrak h\to eqcmathfrak g$ be an inclusion of Lie algebras, let $Z\to eq(cmathop{\wedge}^3cmathfrak g)^{cmathfrak g}$, and let a formal classical dynamical $r$-matrix mean…

Existence conjecture. Any modified dynamical $r$-matrix admits a formal twist quantization.
