On the Kato Decomposition of Quasi–Fredholm and B–Fredholm Operators
We construct a Kato-type decomposition of quasi-Fredholm operators on Banach spaces. This generalizes the corresponding result of Labrousse for Hilbert space operators. The result is then applied to B-Fredholm operators. Denote by B(X) the set of all bounded linear operators acting on a Banach space X. For T ∈ B(X) denote by N(T ) = {x ∈ X : Tx = 0} and R(T ) = TX its kernel and range, respecti...

15 صفحه اولThe Stability Radius of Fredholm Linear Pencils
Let T and S be two bounded linear operators from Banach spaces X into Y and suppose that T is Fredholm and dimN(T − λS) is constant in a neighborhood of λ = 0. Let d(T ;S) be the supremum of all r > 0 such that dimN(T − λS) and codim R(T − λS) are constant for all λ with |λ| < r. It is a consequence of more general results due to H. Bart and D.C. Lay (1980) that d(T ;S) = limn→∞ γn(T ;S) , wher...
متن کاملSolving Non-linear Fredholm Integro-differential Equations
In this paper, Semi-orthogonal (SO) B-spline scaling functions and wavelets and their dual functions are presented to approximate the solutions of linear and non-linear second order Fredholm integro-differential equations. The B-spline scaling functions and wavelets, their properties and the operational matrices of derivative for this functions are presented to reduce the solution of linear and...
متن کاملNumerical solution of linear Fredholm integral equations
In this paper, numerical solution of linear Fredholm integral equations of the second kind is considered by two methods. The methods are developed by means of the Sinc-collocation method and shifted Chebyshev polynomial method. Some numerical examples are presented to illustrate the method. Numerical solution of linear Fredholm integral equations. 1. Introduction Many initial and boundary value...
