WebFor two Hermitian matrices A and B, at least one of which is positive semidefinite, we give upper and lower bounds for each eigenvalue of AB in terms of the eigenvalues of A and B. For two complex matrices A, B with known singular values, upper and lower bounds are deduced for each singular value of AB. Download to read the full article text. WebQuestion: Let A=(103408) (a) Find the eigenvalues of A and, for each eigenvalue, find a corresponding eigenvector of the form (ab), where a,b are integers and b>0. (b) Hence express A in the form PDPP−1, where P is an invertible matrix and D is a diagonal matrix, stating the matrices P,P−1 and D. (c) Use your answer to part (b) to calculate A4.

This is the meaning when the vectors are in. The formal definition of eigenvalues and eigenvectors is as follows.
