Gale Duality and Koszul Duality
Given a hyperplane arrangement in an affine space equipped with a linear functional, we define two finite-dimensional, noncommutative algebras, both of which are motivated by the geometry of hypertoric varieties. We show that these algebras are Koszul dual to each other, and that the roles of the two algebras are reversed by Gale duality. We also study the centers and representation categories ...
متن کاملPoincaré/koszul Duality
We prove a duality for factorization homology which generalizes both usual Poincaré duality for manifolds and Koszul duality for En-algebras. The duality has application to the Hochschild homology of associative algebras and enveloping algebras of Lie algebras. We interpret our result at the level of topological quantum field theory.
متن کاملChiral Koszul Duality
We extend the theory of chiral and factorization algebras, developed for curves by Beilinson and Drinfeld in [BD1], to higher-dimensional varieties. This extension entails the development of the homotopy theory of chiral and factorization structures, in a sense analogous to Quillen’s homotopy theory of differential graded Lie algebras. We prove the equivalence of higherdimensional chiral and fa...
متن کاملLinear Koszul Duality
In this paper we construct, for F1 and F2 subbundles of a vector bundle E, a “Koszul duality” equivalence between derived categories of Gm-equivariant coherent (dg-)sheaves on the derived intersection F1 R ∩EF2, and the corresponding derived intersection F ⊥ 1 R ∩E∗F ⊥ 2 . We also propose applications to Hecke algebras.
متن کاملKoszul Duality for Dioperads
We introduce the notion of a dioperad to describe certain operations with multiple inputs and multiple outputs. The framework of Koszul duality for operads is generalized to dioperads. We show that the Lie bialgebra dioperad is Koszul. The current interests in the understanding of various algebraic structures using operads is partly due to the theory of Koszul duality for operads; see eg. [K] o...
