Let A be an invertible linear operator on a finite-dimensional complex vector space V. Recall that we have shown in class that in this case, there exists a unique unitary operator U such that A=UA. The point of this exercise is to prove the following result: an invertible operator A is normal if and only if U|A= |AU. a) Show that if UA = |A|U, then AA* = A*A. Now, we want to show the other direction, i.e. if AA*...

Outline a proof of the following statement by writing the "starting point" and the "conclusion to be shown" in a proof of the statement: For all integers a, b, and c, if a b and ac, then a (5b + 3c). That is, complete the sentences below. Proof: Assume We must show that Assume that a(5b + 3c); We must show that alb, and alc. Oa Assume a = 2, b=6, c=12; We must show...
