What is it about?
A variation of the a-Weyl theorem is performed by changing the upper Weyl spectrum to the upper Fredholm spectrum.

Why is it important?
This study is important because it allows us to generalize the a-Weyl theorem and to open a new avenue in the local spectral theory, which has several applications.
Perspectives
As described in the article, innovations in local spectral theory and studies on generating new spectral equations are still pending.
