Definition of "foliation" in inglés

noun

1. (botany) The process of forming into a leaf or leaves.

2. (publishing) The process of forming into pages; pagination.

3. (codicology, publishing) The numbering of the folios of a manuscript or a book.

4. (botany) The manner in which the young leaves are disposed within the bud.

5. The act of beating a metal into a thin plate, leaf, foil, or lamina.

6. The act of coating with an amalgam of tin foil and quicksilver, as in making looking-glasses.

7. The enrichment of an opening by means of foils, arranged in trefoils, quatrefoils, etc.; also, one of the ornaments.

8. (geology) The property, possessed by some crystalline rocks, of being divided into plates or layers, due to the cleavage structure of one of the constituents, as mica or hornblende. It may sometimes include slaty structure or cleavage, though the latter is usually independent of any mineral constituent, and transverse to the bedding, it having been produced by pressure.

   • They show that curved inclusion trails may form even with no coupling, as the porphyroblast overgrows foliation that is deflected around it.

9. (topology) A set of submanifolds of a given manifold, each of which is of lower dimension than it, but which, taken together, are coextensive with it.

   • We will show that every closed 3-manifold has a foliation of codimension one. In 1952, G. Reeb published his construction of a foliation of the 3-sphere. About twelve years later, W. Lickorish [123] exhibited foliations of codimension one on every closed, orientable 3-manifold.
   • The simplest example of a foliation is provided by a single submersion F : M → N, M and N being manifolds.
