Normed vector spaces
... Examples 3.11. The following are Hilbert spaces, when equipped with their usual inner products: Fn ; `2 (S), where S is a set; and L2 (M ), where M is a measure space. We showed that `p (S) is complete in Topic 2; in particular, `2 (S) is complete. The case of L2 (M ) is similar, but requires integr ...

Theorem: If f(x) is continuous on a closed interval [a, b] and f(a) f(b), then for every value M between f(a) and f(b), there exists at least one value c (a, b) such that f(c) = M. *Corollary: If f(x) is continuous on [a, b] and if f(a) and f(b) are nonzero and have opposite signs, then f(x) has ...

CHAPTER IV NORMED LINEAR SPACES AND BANACH SPACES
... THEOREM 4.8. Let X be a Banach space, let Y be a normed linear space, let {Tn } be a sequence of elements of L(X, Y ), and suppose that {Tn } converges pointwise to a function T : X → Y. Then T is a continuous linear transformation of X into Y ; i.e., the pointwise limit of a sequence of continuous ...

... 1.1. Why functions? This section is more about the gameplan and general philosophy that we’ll follow. The basic premise (which many may find disagreeable) is the following: We are interested in the functions of certain types from certain kinds of spaces, to R or C. We’re not interested in a function ...
