Basic Functional Analysis,ome fundamental concepts of functional analysis, which we will start to develop now. We shall use these functional-analytic tools also in later parts of this book in some of our convergence and error analysis for the approximate solution of differential and integral equations.

Ill-Conditioned Linear Systems,tion should depend continuously on the data. The third postulate is motivated by the fact that in general, in applications the data will be measured quantities and therefore always contaminated by errors. A problem satisfying all three requirements is called.Otherwise, it is called.a bounded linear

Iterative Methods for Nonlinear Systems,general, available for nonlinear equations, and hence their solution completely relies on iterative methods. In the first section we shall begin with the application of the Banach fixed point theorem for systems of nonlinear equations with one or several variables. Given the fact that iterative tech

Boundary Value Problems,l equations are problems in which the solution is required to satisfy conditions at more than one point, usually at the two endpoints of the interval in which the solution is to be found. Since an ordinary differential equation of order.has, in principle, a general solution depending on.parameters,
