Query: Constraining Slow-Roll Inflation in the Presence of Dynamical Dark
  Energy   In this paper we perform a global analysis of the constraints on the
inflationary parameters in the presence of dynamical dark energy models from
the current observations, including the three-year Wilkinson Microwave
Anisotropy Probe (WMAP3) data, Boomerang-2K2, CBI, VSA, ACBAR, SDSS LRG, 2dFGRS
and ESSENCE (192 sample). We use the analytic description of the inflationary
power spectra in terms of the Horizon-flow parameters $\{\epsilon_i\}$. With
the first order approximation in the slow-roll expansion, we find that the
constraints on the Horizon-flow parameters are $\epsilon_1<0.014 (95% C.L.)$
and $\epsilon_2=0.034\pm0.024 (1\sigma)$ in the $\Lambda$CDM model. In the
framework of dynamical dark energy models, the constraints become obviously
weak, $\epsilon_1<0.022 (95% C.L.)$ and $\epsilon_2=-0.006\pm0.039 (1\sigma)$,
and the inflation models with a "blue" tilt, which are excluded about $2\sigma$
in the $\Lambda$CDM model, are allowed now. With the second order
approximation, the constraints on the Horizon-flow parameters are significantly
relaxed further. If considering the non-zero $\epsilon_3$, the large running of
the scalar spectral index is found for the $\Lambda$CDM model, as well as the
dynamical dark energy models.
