Odd Khovanov homology for hyperplane arrangements

Dancso, Zsuzsanna; Licata, Anthony


We define several homology theories for central hyperplane arrangements, categorifying well-known polynomial invariants including the characteristic polynomial, Poincaré polynomial, and Tutte polynomial. We consider basic algebraic properties of such chain complexes, including long-exact sequences associated to deletion-restriction triples and dg-algebra structures. We also consider signed hyperplane arrangements, and generalize the odd Khovanov homology of Ozsváth-Rasmussen-Szabó from link...[Show more]
