Webindeed, the Bolzano{Weierstrass theorem states that closed bounded subsets of the real line are sequentially compact. And nally, let us make another de nition: A metric space (X;d) is said to be totally bounded(or precompact) if, for every > 0, the space X can be covered by a nite family of open balls of radius . Webcontinuous if and only if for every bounded sequence (Uk) with Uk E D, the sequence (T (Uk)) has a convergent subsequence. Notice that any completely continuous operator is a bounded operator. Theorem 2.1 (1) If the operators TI , T2 : D c X ---> Yare bounded (completely continuous) then for every a, f3 E R the operator aTl + f3T2 is Webmetric. In this case, Z is actually bounded (e.g. it is contained in B(0,2)) but it is not totally bounded (it is not possible to cover Z by balls of radius 1/2). Exercise 3.4.

Web4. Let X be a topological space. A closed set A ⊆ X is a set containing all its limit points, this might be formulated as X ∖ A being open, or as ∂ A ⊆ A, so every point in the boundary of A is actually a point of A.
