Abstract
We study the -pseudospectra of square matrices . We give a complete characterization of the -pseudospectra of matrices and describe the asymptotic behavior (as ) of for every square matrix . We also present explicit upper and lower bounds for the -pseudospectra of bidiagonal matrices, as well as for finite-rank operators.
