LeRoy B. Beasley, Sang‐Gu Lee, You-Ho Lee · Kyungpook mathematical journal · 1999
In this paper, we will investigate the set of linear operators that strongly preserve multivariate majorization with some additional conditions. We determine the linear operators that strongly preserve multivariate majorization with T(I) = I and which map nonnegative matrices to nonnegative matrices.
