Query: Stability of de Sitter solutions sourced by dark spinors   Cosmology of ELKO and Lorentz Invariant NSS has been investigated using
dynamical system method starting from the proposal of Boehmer et al
[arXiv:1003.3858]. Some different results have been obtained by a different
approach. The exact solutions described by fixed points of the dynamical system
and their stability have been discussed. Some stable solutions corresponding to
de Sitter universes have been obtained.
