The latter is the convex hull of top rank valuation vectors of sections, all with respect to a single flag. In this text we give a different volume formula, valid in the ample cone, also based on top rank valuation vectors, but mixing data along several different flags.", "revisions": [ { "version": "v1", "updated": "2019-03-11T14:17:13.000Z" } ], "analyses": { "subjects": [ "14C20", "13F30" ], "keywords": [ "okounkov body", "rank valuation vectors", "big line bundle", "ample cone", "euclidean volume" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
