Watch later. Share. Fredholm theory An operator T ∈ B ( H ) is called upper semi-Fredholm if null( T ) < ∞ and T ( H ) is closed, while T ∈ B ( H ) is called lower semi-Fredholm if def( T ) < ∞ . Fredholm, he ﬁrst develops a complete theory for linear systems and eigensystems and then by a limiting process generalizes the theory to (1.1). He is forced to assume that his eigenvalues are not multiple (although he relaxes this assumption toward the … Fredholm published a fuller version of his theory of integral equations in Sur une classe d'équations fonctionelle Ⓣ which appeared in Acta Mathematica in 1903. Hilbert extended Fredholm's work to include a complete eigenvalue theory for the Fredholm integral equation.

A linear integral equation is the continuous analog of a system of linear algebraic equations. Soon after Volterra began to promote this productive idea, Fredholm proved that one of the most important facts about a system of linear algebraic equations is still true for linear integral equations of a certain type: If the solution is unique whenever there is a solution, then in fact

This thesis is about Fredholm theory in a Banach algebra relative to a ﬁxed Banach algebra homomorphism – a generalisation, due to R. Harte, of Fred-holm theory in the context of bounded linear operators on a Banach space. Only complex Banach algebras are considered in this thesis. Key words: Fredholm, Weyl and Browder elements, spectral theory, spectral radius, holomorphic functional calculus. 1. Introduction In the early 1980’s Harte [10] introduced Fredholm, Weyl and Brow-der theory relative to a unital homomorphism T : A!B between general unital Banach algebras Aand B.
