**Example text**

For each k quence of (u~k)) and = 2,3, ... , we obtain the se- = 1,2, ... , (u~k+l)) is a subse(36) for all n, m. = . u(n) n· By (36), for all n, m with m ~ n. Therefore, (v n ) is a Cauchy subsequence of (un). Since X is a Banach space, the sequence (v n ) is convergent. This proves the relative compactness of the set M. 2 Compact Operators Definition 11. Let X and Y be normed spaces over IK.

L = span M. Ad (ii). Use a similar argument as in the proof of (i). In this connection, observe that it follows from as well as a1 + ... + an = 1, (31 + ... + (3m = 1, and a + (3 = 1, that aa1 n + ... + aa n + (3(31 + ... + (3(3m = a + (3 = 1. Ad (iii). , U E X such that Un -+ U as -+ 00 Ilun - ull -+ 0 as n -+ 00 and Un E M for all n. (29) We want to show that the set C is closed. To this end, let (v n ) be a sequence in C such that as n -+ 00. Vn -+ V By the definition of C, for each Vn , there is a point Wn E M such that for all n = 1,2, ....

This definition makes sense, since for each given v E Y, there exists exactly one u E M such that Au = v. The set A- 1 (N) := {u E M:Au E N} is called the preimage of the set N. Operators are also called functions. Convention 2. In order to indicate conveniently that the domain of definition M of the operator A: M ---+ Y is contained in the set X, we frequently write A: M ~ X ---+ Y. In particular, if Y functional. = lK, then the operator A: M ~ X ---+ lK is called a Example 3. , where b < 00 and -00 < c < d < 00.
