Shear Mapping - Advanced Form

Advanced Form

For a vector space V and subspace W, a shear fixing W translates all vectors parallel to W.

To be more precise, if V is the direct sum of W and W′, and we write vectors as

v = w + w′

correspondingly, the typical shear fixing W is L where

L(v) = (w + Mw′) + w ′

where M is a linear mapping from W′ into W. Therefore in block matrix terms L can be represented as

with blocks on the diagonal I (identity matrix), with M above the diagonal, and 0 below.

Famous quotes containing the words advanced and/or form:

    How oft when men are at the point of death
    Have they been merry! which their keepers call
    A lightning before death: O, how may I
    Call this a lightning? O my love! my wife!
    Death, that hath sucked the honey of thy breath,
    Hath had no power yet upon thy beauty:
    Thou art not conquered; beauty’s ensign yet
    Is crimson in thy lips and in thy cheeks,
    And death’s pale flag is not advanced there.
    William Shakespeare (1564–1616)

    The sense of an entailed disadvantage—the deformed foot doubtfully hidden by the shoe, makes a restlessly active spiritual yeast, and easily turns a self-centred, unloving nature into an Ishmaelite. But in the rarer sort, who presently see their own frustrated claim as one among a myriad, the inexorable sorrow takes the form of fellowship and makes the imagination tender.
    George Eliot [Mary Ann (or Marian)
