ESSENTIAL SPECTRA OF ORDINARY DIFFERENTIAL OPERATORS II.
STABILITY OF SPECTRA
Keyword(s):
The article contains precise formulas for finding of the essential spectra that are revolted with asymptotically constants on infinity in coefficients with use of rather compact and rather small indignations on infinity in Lebesgue spaces of 𝐿 𝑝 . These formulas are new analogs of the classical theorem of Weyl.
