First, R(A) ⊥ = N(AT). If y ∈ R(A) ⊥ then yTAx = 0 for all x, which implies ATy = 0. Conversely ATy = 0 implies yTAx = 0 for all x, hence y ∈ R(A) ⊥. The double-orthogonal complement R(A) ⊥ ⊥ is R(A), since R(A) is a linear subspace of some finite-dimensional inner product space.

First, recall from elementary linear algebra the “Fredholm alternative theorem” ( e.g., [44]):. Theorem 1.1 (Fredholm's alternative). Given a matrix A ∈ Km×n and a   Fredholm operators and the Fredholm alternative. Problem 4.1.

In mathematics, Fredholm's theorems are a set of celebrated results of Ivar Fredholm in the Fredholm theory of integral equations.There are several closely related theorems, which may be stated in terms of integral equations, in terms of linear algebra, or in terms of the Fredholm operator on Banach spaces. Fredholm alternative. Linear algebra[edit] If V is an n-dimensional vector space and is a linear transformation, then exactly one of the following holds: For each vector v in V there is a vector u in V so that .

A alternativa de Fredholm, termo matemático decorrente de seu formulador Ivar Fredholm, é um dos teoremas de Fredholm e um resultado na teoria de Fredholm. A alternativa pode ser expressa de diversas formas: como um teorema da álgebra linear, um teorema das a equações integrais, ou ainda um teorema dos operadores de Fredholm.

2 Fredholm Alternative The Fredholm Alternative is often considered one of the most important Theorems in applied mathematics (competing with Taylor’s Theorem, among others). It gives a notion of ‘solvability criterion’ for a wide range of linear operators, and has numerous applications in differential and …

40 The Fredholm Alternative of Theorem 5.55 first appeared in the study of what are now known as Fredholm integral equations: in which K(x, y) and f(x) are prescribed continuous functions.

In mathematics, Fredholm's theorems are a set of celebrated results of Ivar Fredholm in the Fredholm theory of integral equations. There are several closely related theorems, which may be stated in terms of integral equations, in terms of linear algebra, or in terms of the Fredholm operator on Banach spaces. The Fredholm alternative is one of the Fredholm theorems.

In mathematics, the Fredholm alternative, named after Ivar Fredholm, is one of Fredholm's theorems and is a result in Fredholm theory. It may be expressed in several ways, as a theorem of linear algebra, a theorem of integral equations, or as a theorem on Fredholm operators.
