Colored DG-operads and homotopy adjunction for DG-categories
Sergey Arkhipov, Tina Kanstrup
Generalizing the approach to pseudo monoidal DG-categories as certain colored non-symmetric DG-operads, we introduce a certain relaxed notion of a category enriched in DG-categorie…
Color Lie rings and PBW deformations of skew group algebras
S. Fryer, T. Kanstrup, E. Kirkman +2
We investigate color Lie rings over finite group algebras and their universal enveloping algebras. We exhibit these universal enveloping algebras as PBW deformations of skew group…
Braid group actions on matrix factorizations
Sergey Arkhipov, Tina Kanstrup
Let be a smooth scheme with an action of a reductive algebraic group over an algebraically closed field of characteristic zero. We construct an action of the extended a…
Equivariant Matrix Factorizations and Hamiltonian reduction
Sergey Arkhipov, Tina Kanstrup
Let be a smooth scheme with an action of an algebraic group . We establish an equivalence of two categories related to the corresponding moment map -…
