abstract = {<p style="text-align: justify;">The gradient of the fluid stresses exerted on curved boundaries, conventionally
computed in terms of directional derivatives of a tensor, is here analyzed by using
the notion of intrinsic derivative which represents the geometrically appropriate tool
for measuring tensor variations projected on curved surfaces. Relevant differences in
the two approaches are found by using the classical Stokes analytical solution for the
slow motion of a fluid over a fixed sphere and a numerically generated three dimensional
dynamical scenario. Implications for theoretical fluid dynamics and for applied
sciences are finally discussed.</p>},
