ABSTRACT

The role of dynamical cosmological Casimir effect to phantom (constant w ) and oscillating universe is discussed. It is shown explicitly that its role is not essential near to Big Rip singularity. However, the account of Casimir fluid makes the scale factor approach to Rip time to be faster. Rip time itself maybe changed too.
