Abstract: | Abstract. While it is well known that the stability of Newtonian flows is determined by the eigenvalues of a linearized equation, there
are no general results of this type for non-Newtonian fluids. In this paper, we show that linear stability of steady creeping
flows of the upper convected Maxwell fluid is indeed determined by the spectrum of the linearized operator. The proof uses
the theory of evolution semigroups over dynamical systems. |
