We give a Brualdi-type Z-eigenvalue inclusion set of tensors, and prove that it is tighter than the inclusion set given by G. Wang, G. L. Zhou, and L. Caccetta [Discrete Contin. Dyn. Syst. Ser. B, 2017, 22: 187–198] in a special case. We also give an inclusion set for lk,s-singular values of rectangular tensors.
Key words： Z-Eigenvalues; digraph; lk; s-singular values; rectangular tensors
