Stability of Left and Right Weyl Essential Spectra
In this work, we use the concept of demicompact linear operators to provide a characterization of the left and right Weyl essential spectra. Additionally, we study the stability of these spectra in Banach space. We illustrate our theoretical results by investigating this type of essential spectra in...
