• TITLE: On the largest principal angle between random subspaces
• AUTHORS: P.-A. Absil, A. Edelman, P. Koev.
• ABSTRACT:
  Formulas are derived for the probability density function and the probability distribution function of the largest canonical angle between two p-dimensional subspaces of R^n chosen from the uniform distribution on the Grassmann manifold (which is the unique distribution invariant by orthogonal transformations of R^n). The formulas involve the gamma function and the hypergeometric function of a matrix argument.
