Bounds on norms of compound matrices and on products of eigenvalues
  An upper bound on operator norms of compound matrices is presented, and special cases that involve the $\ell_1$, $\ell_2$ and $\ell_\infty$ norms are investigated. The results are then used to obtain bounds on products of the largest or smallest eigenvalues of a matrix.
