Query: Fermion Mass Matrices in term of the Cabibbo-Kobayashi-Maskawa Matrix
  and Mass Eigenvalues   A parameter free, model independent analysis of quark mass matrices is
carried out. We find a representation in terms of a diagonal mass matrix for
the down (up) quarks and a suitable matrix for the up (down) quarks, such that
the mass parameters only depend on the six quark masses and the three angles
and phase appearing in the Cabibbo-Kobayashi-Maskawa matrix. The results found
may also be applied to the Dirac mass matrices of the leptons.
