https://doi.org/10.1007/978-3-319-52971-4We now have enough machinery at our disposal to develop one of the most important tools in topology: the degree of a map .: . → ., where M and . are compact .-manifolds, . is connected, and . = . = ?. This degree is an integer if . and . are oriented, an integer mod 2 otherwise.作者: Dawdle 時(shí)間: 2025-3-23 00:10 作者: 過(guò)時(shí) 時(shí)間: 2025-3-23 02:13

Most of the deep invariants of a manifold are intimately linked to the tangent bundle; their development requires a general theory of vector bundles.作者: falsehood 時(shí)間: 2025-3-25 04:32
