Nettet16. feb. 2024 · A generalization of Hodge theory to arbitrary complex algebraic varieties was developed by Deligne [17, 18].He showed that the cohomology of a complex algebraic variety (not necessarily complete or nonsingular) carries a slightly more general structure, which presents \(H^k(X,\mathbb {C})\) as a successive extension of Hodge structures … NettetHODGE THEORY PETER S.
