hyperplane at infinity造句

例句与造句

1. In that case, the intersection point mentioned above lies on the hyperplane at infinity.
2. The locus " t " = 0 is called the hyperplane at infinity.
3. Also, any affine ovoid can be considered a projective ovoid in the projective closure ( adding a hyperplane at infinity ) of the affine space.
4. Thus, parallel hyperplanes, which did not meet in the affine space, intersect in the projective completion due to the addition of the hyperplane at infinity.
5. Further, transformations of projective space that preserve affine space ( equivalently, that leave the hyperplane at infinity invariant as a set ) yield transformations of affine space.
6. It's difficult to find hyperplane at infinity in a sentence. 用hyperplane at infinity造句挺难的
7. Similarly, starting from an affine space " A ", every class of union over all classes of parallels constitute the points of the hyperplane at infinity.
8. The resulting projective subspaces are often called " affine subspaces " of the projective space " P ", as opposed to the "'infinite "'or "'ideal "'subspaces, which are the subspaces of the hyperplane at infinity ( however, they are projective spaces, not affine spaces ).
9. as counting the ( " r "  " 1 )-dimensional subspaces of ( " m "  " 1 )-dimensional projective space by fixing a hyperplane, counting such subspaces contained in that hyperplane, and then counting the subspaces not contained in the hyperplane; these latter subspaces are in bijective correspondence with the ( " r "  " 1 )-dimensional affine subspaces of the space obtained by treating this fixed hyperplane as the hyperplane at infinity.
