SpletThe trace map is the analog for coherent sheaf cohomology of integration in de Rham cohomology. [1] Differential-geometric theorem [ edit] Serre also proved the same duality statement for X a compact complex manifold and E a holomorphic vector bundle. [2] Here, the Serre duality theorem is a consequence of Hodge theory. Spletchoice. The issue arose in defining the trace map. We define the orientation sheaf O R for M to be the local system whose fiber at x2M is Hd(M;Mnx;R) ’ Hd 1(Sd 1;R),whichisnon-canonicallyisomorphictoR.
