In this article, we give some results on the S ‐essential spectra of a linear operator defined on a Banach space. Furthermore, we apply the obtained results to determine the S ‐essential spectra of an integro‐differential operator with abstract boundary conditions in the Banach space L p ([− a , a ] × [−1,1]), p ≥ 1 and a > 0.
