Most of the classical metric spaces with metric "d" have the property that given any two pairs of points a, , a2 , bi, b2 of the space with d(al , a2) = d(b1, b2), there is an isometry of the space carrying a1, a2 to b1, b2 respectively. This property was called two-point homogeneity by Birkhoff [2] and called the (*)-property by Busemann.

Structure of the Two-Point Function
Journal of Mathematical Physics, 1963The two-point functions of relativistic quantum field theory are discussed in the framework of distribution theory. A derivation in this framework of the Källén-Lehmann representation is given. The singularities in x space are studied for the example of the DP function.

A horopter for two-point perspective
SPIE Proceedings, 2005Linear perspective is constructed for a particular viewing location with respect to the scene being viewed and, importantly, the location of the canvas between the viewer and the scene. Conversely, both the scene and the center of projection may be reconstructed with some knowledge of the structure of the scene.

AbstractIt is known that the scattering of a low‐energy particle by a potential of a small radius of action is satisfactorily described by the s‐wave alone. In the present paper we give a method for obtaining functions by means of which the scattering of particle on two localized potentials separated by an arbitrary distance 2d can be described with ...

Temperature and the Two-Point Threshold
Somatosensory & Motor Research, 1989Studies dating back to 1834 have shown that the temperature of objects contacting the skin can substantially intensify their apparent pressure on the skin. Later research demonstrated qualitatively that object temperature can also sharpen the spatial acuity of the skin as revealed by gap perception (two-point and two-edge thresholds).
