DESCRIPTION:Speakers: Olga Sergijenko (Taras Shevchenko National Universit
y of Kyiv)\nWe generalize quintom to include the tachyonic kinetic term al
ong with the classical one. For the spatially flat\, homogeneous and isotr
opic Universe with Friedmann-Robertson-Walker metric of 4-space we discuss
in detail the reconstruction of the scalar fields potential $U(\\phi\,\\x
i)$. Such a reconstruction cannot be done unambiguously\, so we consider 3
simplest forms of $U(\\phi\,\\xi)$: the product of $\\Phi(\\phi)$ and $\\
Xi(\\xi)$\, the sum of $\\Phi(\\phi)$ and $\\Xi(\\xi)$ and this sum to the
$\\kappa$th power. We present the maps of reconstructed potentials for th
e Chevallier-Polarski-Linder parametrization of the equation of state para
meter and the set of cosmological parameters obtained from the latest Plan
ck data.\n\nhttps://indico.bitp.kiev.ua/event/2/contributions/3/
