On fredholm and weyl operators in hilbert spaces

Abstract

This project deals with Fredholm, Weyl and Browder operators in Hilbert spaces. Chapter one is t be int.rorl uct.iou part whore not at ions and detin it ions are gIven. Chapter two tackles Fredholm operators by form of defiuit.ions, st at elfl('llt of theorems. propositions and lemmas. Chapter three deals with \VCy! and Browder operators whic-l: em' .ut uallv cl subset of the class of Fredholm operators and gives some results on them. Finally, chapter four closes this exposition by considering some spectral properties of Fredholm. Wevl and Browder operators
