Abstract

Pseudospectra represent a recent global insight into spectral and stability properties of the non-conservative dynamic systems with nonnormal coefficient matrices of the mathematical models. The estimation of the resolvent norm exploiting only eigenvalues and singular values is investigated in this paper and two other approximate techniques are presented.
