Prove that, for large integer k 〉 0, the 2-norm of an arbitrary matrix Ak behaves...
5. Let AE Maxn(C). Recall that A is said to be nilpo tent if there exists a positive integer k such that A 0. Prove the following statements (a) If A is nilpotent, then A 0. (Hint: First show that if A is nilpotent, then the Jordan form of A is also nilpotent.) (b) If A is nilpotent, then tr(A) 0 (e) A is nilpotent if and only if the characteristic polynomial of A is (-1)"" (d) If A is...
1. If the ax matrix A has eigenvalues ....., what are the eigenvalues of a) 4*, where & is a positive integer. AE? A ' b) ', assuming the inverse matrix exists. c) A' (transpose of ). d) a, where a is a real number. e) Is there any relationship between the eigenvalues of 'A and those of the A matrix? Hint: Use to justify your answer. 2. Compute the spectral norm of 0 0 b) c) c) 1-1 0...
