We use the symbol :, for example, f(x)= r² to say that the function f is defined by setting f(x)=r2 for all in the domain. This is same as writing f(x) do 2.

Hence the emphasis all through had been to look at concrete spaces of function and linear maps between them. This has two advantages: (1) the students get to see the typical applications of the results of functional analysis to other parts of analysis and (2) while dealing with such Fredholm Operators and Index Theory Let T be a Fredholm operator on a Banach space X. Prove that the index of T', defined by index(T) dim(ker(T)) - dim(coker(T)), is stable under compact perturbations, i.e., show that if K is compact, then T + K is Fredholm and index(T+K) = index(T). Use this property to discuss applications in spectral theory, particularly in analyzing essential spectra. Functional Calculus for Normal Operators Define the continuous functional calculus for a normal operator N on a Hilbert space H. Show that for any continuous function f: (N) → C, there exists an operator f(N) such that f(N) respects the functional properties of f (e.g. fi(N) + 2(N) = (1 + f2)(N)). Prove that this calculus preserves the spectrum in the sense that σ(f(N)) = f(σ(N)).
