Abstract
The rates of rotation of material directions in a deforming medium are analyzed. New interpretations of the vorticity vector are obtained by considering averages over various sets of material fibres at a point in the medium. It is shown that the suitable averaging must be weighte d by the geometrical inertia operator.
