Koszul Duality for modules over Lie algebra | | Tomasz Maszczyk
; Andrzej Weber
; | | Date: |
22 Dec 2000 | | Subject: | Algebraic Geometry | math.AG | | Abstract: | Let $g$ be a reductive Lie algebra over a field of characteristic zero. Suppose $g$ acts on a complex of vector spaces $M$ by $i_lambda$ and $L_lambda$, which satisfy the identities as contraction and Lie derivative do for smooth differential forms. Out of this data one defines cohomology of the invariants and equivariant cohomology of $M$. We establish Koszul duality between each other. | | Source: | arXiv, math.AG/0101180 | | Services: | Forum | Review | PDF | Favorites | |
