On coincidence problem and attractor solutions in ELKO dark energy model

Abstract

We study the critical points of a universe dominated by ELKO spinor field dark energy and a barotropic matter without considering a specific potential or interaction. The coincidence problem and attractor solutions are discussed at late time, and it is shown that the coincidence problem can not be solved in this model.Comment: 8 pages. Accepeted by Gen. Rel. Gra
