Equiangular subspaces in Euclidean spaces

23 Jan 2018 Balla Igor Sudakov Benny

A set of lines through the origin is called equiangular if every pair of lines defines the same angle, and the maximum size of an equiangular set of lines in $\mathbb{R}^n$ was studied extensively for the last 70 years. In this paper, we study analogous questions for $k$-dimensional subspaces... (read more)
