Equiangular lines

In geometry, a set of lines is called equiangular if all the lines intersect at a single point, and every pair of lines makes the same angle. (Wikipedia).

Complex Equiangular Lines: The Unusual Shapes of Quantum Physics

How many intersecting lines can you draw such that the angle made by any pair is the same as the angle made by any other pair? What if you try in 3 dimensions, or 4, or 5? What if you let your coordinates become complex numbers? And what does all this have to do with quantum probability?!

Seminar on Applied Geometry and Algebra (SIAM SAGA): Dustin Mixon

Title: Packing Points in Projective Spaces Speaker: Dustin Mixon Date: Tuesday, March 8, 2022 at 11:00am Eastern Abstract: Given a compact metric space, it is natural to ask how to arrange a given number of points so that the minimum distance is maximized. For example, the setting of the

What is an equiangular triangle

👉 Learn the essential definitions of triangles. A triangle is a polygon with three sides. Triangles are classified on the basis of their angles or on the basis of their side lengths. The classification of triangles on the bases of their angles are: acute, right and obtuse triangles. The cl
