Abstract
The qualitative nature of the growth of perturbations associated with the linear stability of inviscid fluid flows has been studied in case of stability of both compressible and incompressible swirling now in a cylindrical tube or annulus and parallel stratified now with or witho ut magnetic field. A new result of substantial mathematical usefulness is obtained. Thus the conditions under which the amplitude of perturb ation u(r) is a decreasing function of the spatial coordinate r are es tablished. (C) Elsevier Science Inc., 1997
