Let $R$ be an elliptic root system, with underlying affine part $R_a$. Let $\tilde{W}(R)$ be its extended Weyl group, let $\tilde{c}$ be a hyperbolic Coxeter element satisfying … a…

Geometric lifting conjecture. The elliptic Artin braid relations admit geometric liftings of fundamental relations such that (i) all inertia groups are trivial and (ii) the $$ -cla…

Let $R$ be the relevant elliptic root system, let $\delta_E$ and $\delta_{\mathrm{pt}}$ be the indicated imaginary-root classes, and let…

Let $s\in HH_0([E/\Gamma])$, let $S$ be the deformation base, and let $M_{\underline\sigma}(v;\mathcal O_{D_\infty})$ be the relative moduli spaces associated to geometric relative…
