Description
In 1958, T. Kato has proved that a closed semi-Fredholm operator A in Banach space can be written A=A1 + A0 where A0 is a nilpotent operator and A1 is a regular one. In J.P. Labrousse has defined and studied quasi-Fredholm operators which are an extension of semi-Fredholm operators. He has also defined the essential quasi-Fredholm spectrum. In this paper we prove the mapping spectral theorem for the essential quasi-Fredholm spectrum concerning bounded operators in Hilbert spaces. (author). 5 refs
