For a non-positive real symmetric matrix,which has a largest zero eigenvalue and at least one negative eigenvalue,we proved that solution starting from outside of unit sphere does not necessarily lead to limit-time overflow,which truly improved the existing convergence results of Oja model for computing dominant eigenvector of real symmetric matrix.
