Dynamical Weyl groups and applications
Pavel Etingof, Alexander Varchenko
Following a preceding paper of Tarasov and the second author, we define and study a new structure, which may be regarded as the dynamical analogue of the Weyl group for Lie algebra…

Difference Equations Compatible with Trigonometric KZ Differential Equations
V. Tarasov, A. Varchenko
The trigonometric KZ equations associated with a Lie algebra $\g$ depend on a parameter $λ\in\h$ where $\h\subset\g$ is the Cartan subalgebra. We suggest a system of dynamical diff…
