Abstract:

A vectorial stationary basic velocity field is considered in a Cartesian basis. Time-dependent vectorial fluctuations are superimposed to yield the perturbed velocity field in a perturbed temperature field. By use of the lemma of Nagumo and Westphal on parabolic differential operators, a pair of upper and lower field bounds are determined for each response function from a set which refers to the data changes within given data bounds.
