Bootstrap equations with restricted SU(3) symmetry and the Cabibbo angle

The bootstrap equations for vector (v) and axial vector (a) octet matrix elements are studied. It is concluded that the equations in their most general form always have solutions with at least two free parameters, so that they may not be used to make unique physical predictions. The need for completeness of sums over repeated indices is questioned. As an example of what happens when the condition of completeness is relaxed, the equations exclusive of terms which represent weak neutral currents, and with no driving terms, are solved to give a Cabibbo angle which is 0.28 without adjustable parameters.
