Stereograph

Definitions

  • Webster's Revised Unabridged Dictionary
    • n Stereograph Any picture, or pair of pictures, prepared for exhibition in the stereoscope. Stereographs are now commonly made by means of photography.

    • n stereograph Same as stereogram.
    • n stereograph A machine for making the embossed or raised points used in New York point-printing for the blind upon sheet-metal plates, the plates being designed for use in an embossing-press for transferring the points (characters, letters, etc.) to paper. It is an adaptation of the kaleidograph and differs from it in employing a fly-wheel, operated by a foot-pedal or other power, to operate the embossing mechanism, the selection of the points and their position being controlled by the operator by means of the keyboard. See kleidograph and point-printing.
    • n stereograph In craniometry, an instrument for drawing orthogonal projections of skulls.

For the purpose of applications, here we describe some fundamental properties of the SU (n) coherent states. (1) Stereographic coordinates The decomposition (31) implies that the SU (n) coherent states may be represented in the complex numbers ζk such that ζk = ei(ϕk+1−ϕk ) tan(ξk ).

The function g has a geometric meaning: it is the stereographic pro jection of the Gauss (or normal) map of the minimal surface ΦW .

Assume that X is contained in a vertical slab (i.e. the vertical component of X is bounded), that the stereographic projection g of the Gauss map of X satisfies g ∼ zα for z → 0 with 0 < α 6= 1, and that the vertical components of the boundary rays are | ˜ϕ−1(πα)|πα apart.

Both of these requirements are met unambiguously (modulo cutoff effects) by overlap fermions: the index theorem as realized by the Ginsparg-Wilson relation gives the topology and the usual definition of the condensate as Σ = (1/Z )∂Z/∂m stereographically maps overlap eigenmodes onto the imaginary axis .
