The dark universe future and singularities: the account of thermal and
  quantum effects
  The knowledge of the universe future is of fundamental importance for any
advanced civilization. We study the future of singular dark universe where
thermal effects due to the Hawking radiation on the apparent horizon of the FRW
universe are taken in consideration. It is shown that dark universe which ends
up at finite-time Type I and Type III singularity or infinite-time Little Rip
singularity transits to finite-time Type II singularity due to account of
thermal effects. On the same time, the Type II and IV singular universe does
not change its qualitative behavior. The combined account of quantum and
thermal effects shows that depending on specific features of the universe only
one of effects is dominant. When (conformal matter) quantum effects are
dominant, the future singularity is usually removed while for dominant thermal
effects the universe final state is the Type II singularity.
