Let Z be the set of T-fixed points of X. We construct a filtration for A(Z), the ring of complex-valued functions on Z, such that Gr A(Z) is isomorphic to the cohomology algebra of X. This is the explanation of the general results of Carrell and Liebermann on the cohomology of T-varities, in the case of toric varieties. We give an explicit isomorphism between Gr A(Z) and Brion's description of the polytope algebra.", "revisions": [ { "version": "v1", "updated": "2003-08-27T23:14:30.000Z" } ], "analyses": { "subjects": [ "14M25", "52B20" ], "keywords": [ "torus action", "fixed points", "cohomology ring", "smooth simplicial toric variety", "polytope algebra" ], "note": { "typesetting": "LaTeX", "pages": 15, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2003math......8266K" } } }
