A conjecture of Kudla relates the arithmetic degrees of top degree special cycles on an integral model of a Shimura variety associated with SO(V) to the coefficients of the central derivative of an incoherent Siegel Eisenstein series of genus m+1. We prove this conjecture for the coefficients of non-singular index T when T is not positive definite. We also prove it when T is positive definite and the corresponding special cycle has dimension 0. To obtain these results, we establish new local arithmetic Siegel-Weil formulas at the archimedean and non-archimedian places.", "revisions": [ { "version": "v1", "updated": "2018-02-26T18:11:36.000Z" } ], "analyses": { "subjects": [ "14G35", "14G40", "11G18", "11F27" ], "keywords": [ "arithmetic degrees", "incoherent siegel eisenstein series", "local arithmetic siegel-weil formulas", "derivative", "positive definite" ], "note": { "typesetting": "TeX", "pages": 59, "language": "en", "license": "arXiv", "status": "editable" } } }
