Summing up the above theory, the first system of equa- tions can be formulated as: � � � x S p S p b j ij ij i� � � � �( )w w a a 0, (18) where � �� � � � � �ij ij ijn S p S p( ) ( )1 w w a a , �ij is again the unit tensor of the second order and � �b n nS nS gi � � � �( )1 � � �s w w a a , see (14).
