J] coincide not only on the affine hyperplane spanned by the facet [bar.
I] vanishes on affine hyperplanes close and parallel to H.
j] lies on the positive side of the affine hyperplane
containing the face [F.
For example, the set of faces of a central or affine hyperplane
arrangement or the set of covectors of an oriented matroid (possibly affine) is a CW left regular band.
Let H an affine hyperplane
orthogonal to the line between x and y that passes through [x + y/2].
exp x [phi] is a locally finite affine hyperplane
arrangement on [Hom.
Here the affine tranposition ((i, j)) corresponds to the reflection in the affine hyperplane
A hyperplane arrangement is a set of hyperplanes, possibly affine hyperplanes
, in V.
G, w) is the following collection of affine hyperplanes
A hyperplane arrangement A (or simply an arrangement) is a finite collection of affine hyperplanes
