Pseudospectra of Wiener-Hopf Integral Operators and Constant-Coefficient Differential Operators
Pseudospectra of Wiener-Hopf Integral Operators and Constant-Coefficient Differential Operators
In this paper, we investigate the ε-pseudospectra of Volterra Wiener-Hopf integral operators and constant-coefficient differential operators with boundary conditions at one endpoint for the interval [0, b].We show that although the spectra of these operators are not continuous in the limit b → ∞, the εpseudospectra are continuous as b …
