The action of operator S (see section 3) on the geo- metrical ribbon graph basis Er or on the Fourier basis Q of K(n) has key properties that will allow us to interpret the dimension of various lattice subspaces of Z|Rib(n)| in terms of sums of products of Kronecker coefficients. ...
The following are some properties of the S-pseudospectrum of an even-order tensor. The results in this section are available in the matrix setting, but the proofs provided here do not involve the matrix unfolding (i.e., using tensor setting only). Remark 5 Let A∈CT2m,n and ϵ>0. ...
