| Abstract: | We review ongoing research related to the asymptotic dynamics of isotropic universes in theories
with higher derivatives, especially near the initial singularity. We treat two major cases, that
is universes in vacuum, and also those filled with radiation using the method of asymptotic
splittings of vector fields. Our solutions have the form of formal Fuchsian-type series for the
basic unknowns and are valid near collapse or big rip regimes asymptotically. |
