# Quasiattractor in models of new and chaotic inflation - General Relativity and Quantum Cosmology

Abstract: Inflation with a scalar-field potential of the form \lambda \phi^2-v^2^2can be described in terms of a parametrical attractor with critical points,whose driftage depends on the control value of the slowly changing Hubble rate.The method allows us to easily obtain theoretical expressions for fluctuationsof inhomogeneity in both the cosmic microwave background and distribution ofmatter. We find the region for admissible values of potential parameters,wherein theoretical predictions are consistent with experimental results withinthe limits of measurement uncertainties.
