RT Book, Section T1 Problemas de algebricidad en topología diferencial A1 Ruiz Sancho, Jesús María A2 Tarrés Freixenet, Juan A2 Montesinos Amilibia, José María AB 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.
