Abstract: It is not yet known if the global attractor of the space L-periodic 2D Navier-Stokes
equations contains nonstationary solutions. Due to the hypothetical existence of such solutions, they were called ghosts. In this work, we introduce and study geometrical structures which are shared by all ghost solutions. This study led us to the consideration of a subclass of ghosts for which those geometrical structures have a supplementary stability property. In particular, we found contraints on the wave vectors of the active modes of the latter ghosts.
