Arithmetic monodromy actions on pro-metabelian fundamental groups of once-punctured elliptic curves

William Yun Chen, Pierre Deligne

We prove structure theorems for the moduli stack of elliptic curves equipped with $G$ -structures, where $G$ is a finite 2-generated metabelian group. In particular, we show that if…

On the $K (π, 1)$ -problem for restrictions of complex reflection arrangements

Nils Amend, Pierre Deligne, Gerhard Roehrle

Let $W \subset G L (V)$ be a complex reflection group, and $A (W)$ the set of the mirrors of the complex reflections in $W$ . It is known that the complement $X({\mathscr A}(…
