Ruiz Sancho, Jesús María 2023-06-20T21:06:06Z 2023-06-20T21:06:06Z 1994 84-7491-510-4 https://hdl.handle.net/20.500.14352/60689 http://cisne.sim.ucm.es/record=b1249015~S6*spi This is a research survey on results dealing with the following question: Let M be a compact smooth manifold and A a family of geometric objects related to M such that there exists some natural equivalence of the pairs (M,A). Does every equivalence class contain some kind of algebraic representative? The survey deals with the cases A = ∅, presenting the achievements of the work of Seifert-Nash-Tognoli, with vector bundles and with realizations of homology classes. In cases of particular interest the methods of proof are outlined. metadata only access Problemas de algebricidad en topología diferencial book part
