Although the general theory of multipliers for abstract Banach algebras has been widely investigated by several authors, it is surprising how rarely various aspects of the spectral theory, for instance Fredholm theory and Riesz theory, of these important classes of operators have been studied.

This paper is based on a lecture given at the Clay Mathematics Institute in 2088, but has been rewritten to take account of recent developments. It focuses on a special case of the theory of Fredholm theory in polyfolds, which allows for boundaries with corners, it focuses on a special and illustrates it with a discussion of stable maps, a topic closely related to Gromov-Witten theory.

Abstract. 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

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.

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. This work led directly to the theory of Hilbert spaces.

This paper presents the Fredholm theory on l p -spaces for band-dominated operators and important subclasses, such as operators in the Wiener algebra. where A is a compact integral operator and f is an element of an appropriately chosen Banach space. The questions of existence and uniqueness of solutions to operator equations of this form are answered by the Riesz–Fredholm theory and hence is the subject matter of this chapter. Fredholm theory.
