Real banach space
WebNormed and Banach spaces In this chapter we introduce the basic setting of functional analysis, in the form of normed spaces and bounded linear operators. We are particularly interested in complete, i.e. Banach, spaces and the process of completion of a normed space to a Banach space. In lectures I proceed to the next chapter, on Lebesgue ...

WebA Banach space (X, ) is a normed vector space (over the real or complex numbers) that is complete with respect to the metric d ( x, y) = x – y . In the sequel, we shall be concerned primarily with such spaces and the (geometrically simpler) special case of Hilbert spaces. Recall that a Hilbert space H is a vector space with a ...
