flag

English

Noun

  1. A piece of cloth, often decorated with an emblem, used as a visual signal or symbol.
  2. An exact representation of a flag (for example: a digital one used in websites).
  3. (nautical) A flag flown by a ship to show the presence on board of the admiral; the admiral himself, or his flagship.
  4. (nautical, often used attributively) A signal flag.
  5. (construction) Abbreviation of flagstone: a construction material used for paving, flooring, roofing or tiling
  6. The use of a flag, especially to indicate the start of a race or other event.
  7. (computer science) A variable or memory location that stores a true-or-false, yes-or-no value, typically either recording the fact that a certain event has occurred or requesting that a certain optional action take place.
  8. (computer science) In a command line interface, a command parameter requesting optional behavior or otherwise modifying the action of the command being invoked.
  9. (Britain) An abbreviation for capture the flag.
  10. (geometry) A sequence of faces of a given polytope, one of each dimension up to that of the polytope (formally, though in practice not always explicitly, including the null face and the polytope itself), such that each face in the sequence is part of the next-higher dimension face.
    • 1994, John Ratcliffe, Foundations of Hyperbolic Manifolds, page 230,
      A flag of P is a sequence (F0, F1, ..., Fm) of faces of P such that dim Fi = i for each i and Fi is a side of Fi+1 for each i < m. [] A regular polytope in X is a polytope P in X whose group of symmetries in <P> acts transitively on its flags.
    • 2002, Peter McMullen, Egon Schulte, Abstract Regular Polytopes, Encyclopedia of Mathematics and Its Applications 92, page 31,
      We call P (combinatorially) regular if its automorphism group Γ(P) is transitive on its flags.
    • 2006, Peter McMullen, Egon Schulte, Regular and Chiral Polytopes in Low Dimensions, Harold Scott Macdonald Coxeter, Chandler Davis, Erich W. Ellers (editors), The Coxeter Legacy: Reflections and Projections, page 91,
      Roughly speaking, chiral polytopes have half as many possible automorphisms as have regular polytopes. More technically, the n-polytope P is chiral if it has two orbits of flags under its group Γ(P), with adjacent flags in different orbits.
  11. (mathematics, linear algebra) A sequence of subspaces of a vector space, beginning with the null space and ending with the vector space itself, such that each member of the sequence (until the last) is a proper subspace of the next.
Synonyms
  • (computer science: true-or-false value): Boolean
  • (computer science: CLI notation): switch
  • (geometry: sequence of faces of a polytope): dart
