Eigenvalues of a transposition: a) Consider the transformation T in the space M2½2 of 2 × 2 matrices, T(A) = AT. Find all its eigenvalues and eigenvectors. Is it possible to diagonalize this transformation? Hint: While it is possible to write a matrix of this linear transformation in some basis, compute characteristic polynomial, and so on, it is easier to find eigenvalues and eigenvectors directly from the definition. b) Can you do the same problem but in the space of n x n matrices?
