Equiangular Cyclic Frames
The complex equiangular cyclic (n, k)-frames have some interesting geometric properties, too. We discuss these in relation to the work on the unresolved Kadison-Singer conjecture.

Equiangular Tight Frames
Equiangular tight frames have arisen in different areas of pure and applied
mathematics. For instance, equiangular tight frames are shown to be optimal
configurations for the Grassmanian line packing problem [18, 19]. It was shown in
[65] and ...

We call a convex polygon equiangular if its angles are congruent. Thus, an
equiangular triangle is an equilateral one, an equiangular quadrilateral is a
rectangle (or a square). One interesting property of the equiangular polygons is

Thus the property of circumscribed circles implies that any Delaunay triangulation
is locally equiangular. Conversely, any locally equiangular triangulation is a
Delaunay triangulation. Indeed, assume that this is wrong and let T be a locally ...
