Let H be a separable Hilbert space with basis en]nen and define P as the orthogonal projection onto span(e,... ,en) (a) A sequence of operators T, E B(H) is said to converge strongly to T if |Th-Tnhl converges to 0 for all h EH (note that strong convergence is actually weaker than operator norm convergence-think of this as the difference between pointwise and uniform convergence). Show that, for any T E B(H), the sequence P,T Pn converges strongly to T....
11. (8)(a) Suppose that f and g are analytic branches of zt on a domain D such that 0 g D Show that there is a fifth root, wo, of 1 such that f(z)-wog(2) for all E D.

in this problem I have a problem understanding the
exact steps, can they be solved and simplified in a clearer and
smoother wayTo understand it .
Q/ How can I prove (in detailes) that the following examples match their definitions mentioned with each of them? 1. Definition 1.4[42]: (G-algebra) Let X be a nonempty set. Then, a family A of subsets of X is called a o-algebra if (1) XE 4. (2) if A € A, then A = X...

Limits and Continuity 4 Chapter Remark: In the statement of Theorem 4.4.12 we assumed that f was tone and continuous on the interval I. The fact that f is either stric tric. strictly decreasing on / implies that f is one-to-one on t one-to-one and continuous on an interval 1, then as a consequence of the value theorem the function f is strictly monotone on I (Exercise 15). This false if either f is...
