ON THE FREDHOLM ALTERNATIVE FOR NONLINEAR FUNCTIONAL EQUATIONS IN BANACH SPACES PETER HESS1 Abstract. The well-known Fredholm alternative theorem for compact linear operators is carried over to a class of noncompact, asymptotically linear mappings of monotone type of a real reflexive Banach space into its dual. An application to a nonlinear About the proof of the Fredholm Alternative theorems Fredholm alternative and solution regularity for time-periodic hyperbolic systems.

In this section, for a p-periodic system (5.1), we use the adjoint equation to obtain necessary and sufficient conditions for the existence of p-periodic solutions of (5.1). We Mathematics Department – Mathematics Department The Fredholm alternative is a classical well-known result whose proof for linear equations of the form (I+ T)u= f, where T is a compact operator in a Banach space, can be found in most texts on functional analysis, of which we mention just [1] and Thus the operator I + K is a semi­Fredholm.Applying the same arguement to the adjoint I + K ∗ completes the proof. Next we give a useful characterization of Fredholm operators. Theorem 16.26. T : X → Y is Fredholm if and only this a bounded linear operator R : Y → X so that RT − I and T R − I are compact operators. 40 Then the Fredholm alternative applies to T = I – U. Proof.

[2] The general version of the Fredholm alternative is best expressed in terms of Fredholm operators. Theorem 3.2 For any compact operator K on E, 1−K is a Fredholm operator of index zero. Before turning to the proofs, let us point out that these results are naturally cast as properties of the spectrum of compact operators 3. 2021-02-23 Let A be a linear bounded operator in a Hilbert space H, N(A) and R(A) its null-space and range, and A∗ its adjoint. The operator A is called Fredholm iff dimN(A)=dimN(A∗):=n<∞ and R(A) and R(A∗) are … cerning the applications of the nonlinear Fredholm alternative, the reader is referred to the monograph [2], or to the more recent papers [9], [8] and their references.) In [7] the generalized Fredholm alternative was applied to prove the existence of a solution to the boundary value problem (BVP for short) (1.1) x0(t)=f(t;x(t)); (1.2) N(x)=r: Theorem 4.1: (Fredholm Alternative) Let Lbe a Sturm-Liouville di erential operator, and consider solutions to L[u] = f(x) with boundary conditions such that Lis self-adjoint. 1.If the only solution to L[u] = 0 satisfying the boundary conditions is u= 0, (that is, if = 0 is not an eigenvalue of L), then there is … 2010-11-12 Proof.
