Let a be a matrix which can be partitioned as follows 10 a3 where a, is an nxn matrix, a, is an mxm matrix, and 0 is a zero matrix (i. e., all its elements are zeros). (a) let a be an eigenvalue of a, with a corresponding eigenvector x. show that a is also an eigenvalues of a with a corresponding eigenvector (6) let b be an eigenvalue of a, with a corresponding eigenvector y. then in general b is also an eigenvalues of a with a corresponding eigenvector express the vector p in terms of a1, a2, a, b and y. (c) when does the statement in (b)not hold?
