A. Yu. Kamenshchik
We investigate particular cosmological models, based either on tachyon fields or on perfect fluids, for which soft future singularities arise in a natural way. Our main result is t…

Darkness without dark matter and energy -- generalized unimodular gravity
A. O. Barvinsky, A. Yu. Kamenshchik
We suggest a Lorentz non-invariant generalization of the unimodular gravity theory, which is classically equivalent to general relativity with a locally inert (devoid of local degr…
