The authors obtain an effective lower bound on the distance of the sum of co-adjoint orbits from the origin. In the particular case of unitary groups, they obtain the quadratic inequality for eigenvalues of Hermitian matrices satisfying \(A+B=C\). This inequality can be interpreted as the Chern number inequality for semi-stable reflexive toric sheaves.
