An approximation principle for congruence subgroups

Tobias Finis, Erez Lapid

The motivating question of this paper is roughly the following: given a group scheme $G$ over $Z_{p}$ , $p$ prime, with semisimple generic fiber $G_{Q_{p}}$ , how far a…

Relation spaces of hyperplane arrangements and modules defined by graphs of fiber zonotopes

Tobias Finis, Erez Lapid

We study the exactness of certain combinatorially defined complexes which generalize the Orlik-Solomon algebra of a geometric lattice. The main results pertain to complex reflectio…
