On residue complexes, dualizing sheaves and local cohomology modules. (English) Zbl 0834.14003
For any variety $$X$$ over a perfect field the authors prove the existence of a natural isomorphism between the Grothendieck residue complex [R. Hartshorne, “Residues and duality”, Lect. Notes Math. 20 (1966; Zbl 0212.261)] and a residue complex described by A. Yekutieli [“An explicit construction of the Grothendieck residue complex”, Astérisque 208 (1992; Zbl 0788.14011)]. As a result they get that the trace map $$\widetilde \vartheta_X$$ defined by J. Lipman [“Dualizing sheaves, differentials and residues on algebraic varieties”, Astérisque 117 (1984; Zbl 0562.14003)] and the trace $$\vartheta_X$$ defined by A. Yekutieli (loc. cit.) agree up to sign. – Then formulas for residues of local cohomology classes of differential forms are written down explicitly. Thus, a clear relation between local cohomology residues and the Parshin residues [see A. Yekutieli (loc. cit.)] is established. It should be remarked that for Cohen-Macaulay varieties similar results were obtained by R. Hübl [Math. Ann. 300, No. 4, 605-628 (1994; Zbl 0814.14022)].
