WebOne of the versions of the Fredholm alternative says that, if K is a compact operator on E, then the associated equation x = Kx+y behaves like in the finite dimensional case: if the homogeneous equation x = Kx has only the trivial solution x = 0, then the inhomogeneous equations x = Kx+y has a unique solution x ∈ E, for every y ∈ E.

Ramm, "A Simple Proof of the Fredholm Alternative and a Characterization of the Fredholm Operators", American Mathematical Monthly, 108 (2001) p. 855 (NB: In this paper the word "Fredholm operator" refers to "Fredholm operator of index 0").

WebOne might suspect, then, that the Fredholm alternative is another in the growing list of properties of the usual (p = 2) Laplacian that permits extension to the case p 6= 2. Actually, we shall show the opposite, namely, that the counterpart of Theorem A (ii) for the p-Laplacian fails when p 6= 2, except for the Neumann boundary conditions. Webof the Fredholm Alternative as stated in the forthcoming Remark 3.2). 2 Fredholm Operators Let B∞[H] be the (two-sided) ideal of all compact operators from B[H]. An operator T in B[H] is left semi-Fredholm if there exists S ∈ B[H] and K ∈ B∞[H] such that ST = I +K, and right semi-Fredholm if there exists S ∈ B[H] and K ∈ B∞[H] such
Web1 Aug 2013 · The aim of this paper is to give an extended version of the Fredholm alternative, by including the B-Fredholm case. Thus if T a B-Fredholm operator acting on a Banach space, we study equations of the type T ( x ) = y , for x , y elements of the range R ( T n ) of T for $${n \\in \\mathbb{N}}$$ . In this study we include the case when 0 is a pole of … WebGive an example of a bounded linear operator that satis es the Fredholm alternative. Problem 14. Let (M;d) be a complete metric space (for example a Hilbert space) and let f: M!Mbe a mapping such that d(f(m)(x);f(m)(y)) kd(x;y); 8x;y2M for some m 1, where 0 k<1 is a constant. Show that the map fhas a unique xed point in M. Problem 15.

Web§ 5 The Fredholm alternative. In this section we give conditions that a continuous linear operator T, mapping a B-space X into itself, must satisfy for the Fredholm alternative to be valid for it (see 1.4). It turns out, in particular, that if some power U m of a linear operator U is compact, then the Fredholm alternative is valid for T = I − U. home purchase processWeb1 Jan 2008 · A. G.
