Definitions

  • WordNet 3.6
    • n syzygy the straight line configuration of 3 celestial bodies (as the sun and earth and moon) in a gravitational system
    • ***
Webster's Revised Unabridged Dictionary
  • Interesting fact: Syzygy is the term referring to when the moon is in a direct line with the earth and the sun. The average person knows this time to be a full or new moon.
    • Syzygy (Zoöl) Any one of the segments of an arm of a crinoid composed of two joints so closely united that the line of union is obliterated on the outer, though visible on the inner, side.
    • Syzygy (Gr. & L. Pros) The coupling together of different feet; as, in Greek verse, an iambic syzygy .
    • Syzygy (Zoöl) The immovable union of two joints of a crinoidal arm.
    • Syzygy The intimately united and apparently fused condition of certain low organisms during conjugation.
    • Syzygy (Astron) The point of an orbit, as of the moon or a planet, at which it is in conjunction or opposition; -- commonly used in the plural.

    • n syzygy In astronomy, the conjunction or opposition of a planet with the sun, or of any two of the heavenly bodies. On the phenomena and circumstances of the syzygies depends a great part of the lunar theory.
    • n syzygy In ancient prosody, a group or combination of two feet. Ancient metricians varied in their use of this term. Some use it regularly for a dipody or (dipodic) measure. Others call a tautopody, or double foot, a dipody, but a combination of two different feet a syzygy. Some, accordingly, giving the name syzygy to tetrasyllabic feet (regarded by them as composed of two dissyllabic feet), speak of an iambic or a trochaic line as measured by dipodies, but an Ionic line as measured by syzygies—that is, by single Ionics considered as combinations of trochees and pyrrhics. A peculiar use is the restriction of the term syzygy to compound feet of five or six syllables.
    • n syzygy In algebra, a linear function in the variables. See syzygetic.
    • n syzygy In zoology, the conjunction of two organs or organisms by close adhesion and partial concrescence, without loss of their identity; also, the thing so formed, or the resulting conformation; a syzygium: a term variously applied. Zygosis or conjugation, as observed in various protozoans and other low organisms. See conjugation, 4, Diplozoön, and diporpa.

    • n Syzygy siz′i-ji the relative position of a planet (esp. the moon) when either in conjunction or in opposition with the sun: the period of new or full moon

In science:

Then the kth syzygies of rank k + 2 are called scrollar syzygies.
Geometric Syzygies of Mukai Varieties and General Canonical Curves with Genus at most 8
Scrollar syzygies are the easiest example of the geometric syzygies constructed by Green and Lazarsfeld in [GL84].
Geometric Syzygies of Mukai Varieties and General Canonical Curves with Genus at most 8
For special canonical curves it is important to consider the non reduced scheme structure on the space of scrollar syzygies as can be seen in the case of a curve of genus 6 with only one g1 5 [AH81, p. 174].
Geometric Syzygies of Mukai Varieties and General Canonical Curves with Genus at most 8
Also there are geometric kth-syzygies in the sense of Green and Lazarsfeld [GL84] which are not of rank k + 2.
Geometric Syzygies of Mukai Varieties and General Canonical Curves with Genus at most 8
Then all minimal rank syzygies are scrollar.
Geometric Syzygies of Mukai Varieties and General Canonical Curves with Genus at most 8
But by the corollary above there are no scrollar syzygies in step k > ⌈ g−5 2 ⌉.
Geometric Syzygies of Mukai Varieties and General Canonical Curves with Genus at most 8
Therefore there can be no syzygies at all in theses steps.
Geometric Syzygies of Mukai Varieties and General Canonical Curves with Genus at most 8
Then the scrollar ⌈ g−5 2 ⌉th syzygies of C are called the last scrollar syzygies of C .
Geometric Syzygies of Mukai Varieties and General Canonical Curves with Genus at most 8
Consider the vector bundle of linear forms L on the variety of Ymin of last scrollar syzygies.
Geometric Syzygies of Mukai Varieties and General Canonical Curves with Genus at most 8
It is well known that such a general linear section has syzygy spaces of the same dimension as X .
Geometric Syzygies of Mukai Varieties and General Canonical Curves with Genus at most 8
So one can consider a syzygy s of X also as a syzygy of X ∩ P(W ).
Geometric Syzygies of Mukai Varieties and General Canonical Curves with Genus at most 8
The rank of this syzygy can change however, if P(W ) does not intersect the zero locus Zs of s in the expected codimension.
Geometric Syzygies of Mukai Varieties and General Canonical Curves with Genus at most 8
Lets first consider the dimensions of the spaces of linear syzygies.
Geometric Syzygies of Mukai Varieties and General Canonical Curves with Genus at most 8
Since dim V = 5 this gives the above syzygy numbers.

The last scrollar syzygies of C are first syzygies of rank 3.
