Please solve this question. Sorry please neglect the bottom picture which says "moreover ...". I am happy to upbote if you solve (1)-(5). Problem 1. We denote by the set of all sequences (UK)x=1,2,... = (U1, U2, ...) (ux E C) u= satisfying luxl <00. Moreover, we define k=1 (u, v) = xox(u, v E f). k=1 (1) Prove that is a vector space. (2) Prove that is a inner product space with respect to (5.). (3) Construct the norm...
Both part of the question is True or False. Thank you Problem 1. (ref. Example 3 in the slide) Let X = Y = C[0, 1] (with the norm || ||C[0,1] = sup |u(x)]). For any u € C[0, 1], define T€[0,1] v(t) = u(s)ds. We denote by T the mapping from u to v with D(T) = C[0, 1], i.e., v(t) = Tu(t). Then, the following conditions are true or not? Example 3. We denote by the set of...
