WebThis procedure can be generalized to the case of a general Mueller matrix. The Hermitian matrix is often called the correlation matrix, H. Simon went on to show that a necessary and sufficient condition for a Mueller matrix to be deterministic is that H has a single non-zero positive eigenvalue and that H = t r (H) H, where tr is the trace of a ... WebFurthermore, if hE,'i is a Hermitian space, the equal-ity holds i↵ u and v are linearly dependent, where in addition, if u 6=0 and v 6=0 , then u = v for some real such that >0. As in the Euclidean case, if hE,'i is a Hermitian space, the Minkovski inequality p (u+v) p (u)+ p (v) shows that the map u 7! p (u)isanorm on E.
