The Pseudospectrum of Systems of Semiclassical Operators
Författare
Summary, in English
In this paper we study the pseudospectrum (spectral instability) of non-selfadjoint semiclassical systems of principal type, generalizing the results in the scalar case by Dencker, Sjostrand and Zworski in Comm. Pure Appl. Math. 57:3 (2004), 384-415.
