Co-rotational time flux

To summarise, we have from equations (4.22), (4.23), (4.25) and (4.26) that the quantities v, Vv, W and h do not satisfy the principle of material frame-indifference, while from equations (4.18), (4.24) and (4.27) we see that the director n, the rate of strain tensor A and the co-rotational time flux N are frame-indifferent and therefore objective. For later ease of reference, we record that... 

Therefore, by the definitions of the relative angular velocity u and the co-rotational time flux N in equations (4.2) and (4.8), respectively, equation (4.76) leads to an equivalent formulation of the left-hand side of inequality (4.61) given by...
