On contact loci of hyperplane arrangementsAdvances in Applied Mathematics - Tập 132 - Trang 102271 - 2022
Budur Nero, Tue Tran Quang
We give an explicit expression for the contact loci of hyperplane arrangements
and show that their cohomology rings are combinatorial invariants. We also give
an expression for the restricted contact loci in terms of Milnor fibers of
associated hyperplane arrangements. We prove the degeneracy of a spectral
sequence related to the restricted contact loci of a hyperplane arrangement and
which conjec... hiện toàn bộ
