NettetWe say that Lefschetz data as above satis es the Hodge-Riemann bilinear relations if all 2V ample do. Remark 2.2. The set of 2V which satisfy hard Lefschetz is Zariski open and stable under multiplication by . The set of 2V which satisfy the Hodge-Riemann bilinear relations is an open semi-algebraic set stable under multiplication by >0. 2.2. NettetNew ingredients in our proof include an integration of Timorin's mixed Hodge–Riemann bilinear relation and a mixed norm version of Hörmander's L2-estimate, which also implies a non-compact version of the Khovanskiĭ–Teissier inequality.
