Resumo

The purpose of this paper is to present an example of an Ordinary Differential Equation x' = F(x) in the infinite-dimensional Hilbert space l(2) with F being of class C-1 in the Frechet sense, such that the origin is an asymptotically stable equilibrium point but the spectrum of the linearized operator DF(0) intersects the half-plane R(z) > 0. The possible existence or not of an example of this kind has been an open question until now, to our knowledge. An analogous example, but of a non-invertible map instead of a flow defined by an ODE was recently constructed by the authors in Rodrigues and Sola-Morales (J. Differ. Equ. 269:1349-1359, 2020). The two examples use different techniques, but both are based on a classical example in Operator Theory due to S. Kakutani. (AU)
