Аннотация:We study the possibility to constrain deviations from Lorentz invariance in dark matter
(DM) with cosmological observations. The homogeneous expansion of the Universe with
Lorentz violating (LV) DM is found to be practically indistinguishable from the standard
ΛCDM cosmology. On the other hand, the evolution of the cosmological perturbations
significantly differs from the standard case. We discuss, at which level this type of deviations
from Lorentz invariance is constrained by the present-day and upcoming cosmological
observations.
