NounEdit

sheaf (plural sheaves or sheafs)

  1. A quantity of the stalks and ears of wheat, rye, or other grain, bound together; a bundle of grain or straw.
    • 1593, William Shakespeare, Titus Andronicus, Act V, Scene III, line 70:
      O, let me teach you how to knit again / This scattered corn into one mutual sheaf, / These broken limbs again into one body.
    • c. 1697, John Dryden, “Georgic I”, in The Works of Virgil:
      E’en while the reaper fills his greedy hands, / And binds the golden sheaves in brittle bands
  2. Any collection of things bound together; a bundle.
    • 1986, John le Carré, A Perfect Spy:
      Together the two men march up the aisle and mount the dais, and while Muspole shakes hands with the chairman and his lady, the major draws a sheaf of notes from a briefcase and lays them on the table.
    a sheaf of paper
  3. A bundle of arrows sufficient to fill a quiver, or the allowance of each archer.
    • 1700, John Dryden, Palamon and Arcite:
      The sheaf of arrows shook, and rattled in the case.
  4. A quantity of arrows, usually twenty-four.
    • 1786, Francis Grose, A Treatise on Ancient Armour and Weapons, page 34:
      Arrows were anciently made of reeds, afterwards of cornel wood, and occasionally of every species of wood: but according to Roger Ascham, ash was best; arrows were reckoned by sheaves, a sheaf consisted of twenty-four arrows.
  5. (mechanical) A sheave.
  6. (mathematics) An abstract construct in topology that associates data to the open sets of a topological space, together with well-defined restrictions from larger to smaller open sets, subject to the condition that compatible data on overlapping open sets corresponds, via the restrictions, to a unique datum on the union of the open sets.
    • Sometimes, it can be useful to use an alternative approach to endow a manifold with a Ck-structure. Here k = 1, 2, ..., ∞, or ω for real analytic manifolds. Instead of considering coordinate charts, it is possible to start with functions defined on the manifold itself. The structure sheaf of M, denoted Ck, is a sort of functor that defines, for each open set U ⊂ M, an algebra Ck(U) of continuous functions U → R.   —Wikipedia
