The signed Varchenko Determinant for Complexes of Oriented Matroids
Winfried HochstättlerSophia KeipKolja Knauer
文献摘要
We generalize the (signed) Varchenko matrix of a hyperplane arrangement to complexes of oriented matroids and show that its determinant has a nice factorization. This extends previous results on hyperplane arrangements and oriented matroids.
