WebWhen a tensor is symmetric, the n-mode product is independent of the mode, i.e. T nv= T mvfor any 1 n;m k. Using this fact, we can have a de nition of symmetric tensor eigenvectors and eigenvalues in which we only need one n-mode product. In this case, we choose n= 1. Definition 2.4(Tensor Eigenvectors and Eigenvalues). Let T2Rd be a tensor Recall that the geometric multiplicity of an eigenvalue can be described as the dimension of the associated eigenspace, the nullspace of λI − A. The algebraic multiplicity can also be thought of as a dimension: it is the dimension of the associated generalized eigenspace (1st sense), which is the nullspace of the matrix (λI − A) for any sufficiently large k. That is, it is the space of generalized eigenvectors (first sense), where a generalized eigenvector is any vector which eventually beco…
