[PDF][PDF] Perron-Frobenius theory on the higher-rank numerical range for some classes of real matrices
M Zangiabadi, H Afshin - Journal of Mahani Mathematical Research, 2021 - academia.edu
We present an extension of Perron-Frobenius theory to the higher-rank numerical range of
real matrices. We define a new type of the rank-k numerical radius for real matrices, ie, the …
