This technique in turn gives information on Betti numbers of holomorphic symplectic quotients. As a consequence, simple unified proofs are obtained for formulas of Poincaré polynomials of toric hyperkähler varieties (recovering results of Bielawski-Dancer and Hausel-Sturmfels), Poincaré polynomials of Hubert schemes of points and twisted Atiyah-Drinfeld-Hitchin-Manin (ADHM) spaces of instantons on ℂ2 (recovering results of Nakajima-Yoshioka), and Poincaré polynomials of all Nakajima quiver varieties. As an application, a proof of a conjecture of Kac on the number of absolutely indecomposable representations of a quiver is announced.","lang":"eng"}],"month":"04","title":"Betti numbers of holomorphic symplectic quotients via arithmetic Fourier transform","author":[{"last_name":"Hausel","first_name":"Tamas","id":"4A0666D8-F248-11E8-B48F-1D18A9856A87","full_name":"Tamas Hausel"}],"date_created":"2018-12-11T11:52:10Z","date_published":"2006-04-18T00:00:00Z","page":"6120 - 6124","doi":"10.1073/pnas.0601337103","issue":"16","oa":1,"publication_status":"published","extern":1,"year":"2006","publication":"PNAS"}
