ON THE M-EIGENVALUE ESTIMATION OF FOURTH-ORDER PARTIALLY SYMMETRIC TENSORS

摘要

In this article, the M-eigenvalue of fourth-order partially symmetric tensors is estimated by choosing different components of M-eigenvector. As an application, some upper bounds for the M-spectral radius of nonnegative fourth-order partially symmetric tensors are discussed, which are sharper than existing upper bounds. Finally, numerical examples are reported to verify the obtained results.
