Cascade Global Symmetry and Quark Mass Hierarchy

Abstract

Cascade global symmetry and multi-vacuum expectation values are combined to produce an {\bf initial} texture of the quark mass matrices. Required corrections to the initial texture zeros ({\bf ITZ)} are all at the order of $10^{-3}{m}_t$ or less. The possibility of {\bf radiative corrections} as the source of the complete mass matrices is briefly discussed.
