| These findings show the importance of the two fundamental features of knee ligament reconstructions: isometry, and graft fixation. |
|
| In the matter of isometry and non-isometry, cartography illustrates the difficulties in trying to represent a sphere on a plane. |
|
| This mapping is not an isometry, for the light cones are tilted, which corresponds to anisotropic light propagation. |
|
| In the constructive theory of linear codes, we can restrict attention to the isometry classes of indecomposable codes, as it was shown by Slepian. |
|
| Display of various views, isometry and vanishing point. |
|
| In a semiregular tessellation, there is an isometry of the plane carrying any vertex to any other vertex. |
|
| But this isometry does not apply to all the geodesics of the surface. |
|
| Thurston also took up ideas about the discrete isometry groups of hyperbolic three-space, first investigated by Henri Poincaré and later studied by Lars Ahlfors. |
|
| A general Riemannian space admits of no isometry other than the identity. |
|
| While an isometry from one metric space to another is a distance preserving map, a quasi-isometry is a map which preserves distances to within fixed linear bounds. |
|
| Isometry helps recover amplitudes thanks to constant and non-excessive tension on the graft, from stretching to complete flexing of the knee. |
