Anisotropic Power-law Inflation
arXiv:1010.5307 · doi:10.1088/1475-7516/2010/12/024
Abstract
We study an inflationary scenario in supergravity model with a gauge kinetic function. We find exact anisotropic power-law inflationary solutions when both the potential function for an inflaton and the gauge kinetic function are exponential type. The dynamical system analysis tells us that the anisotropic power-law inflation is an attractor for a large parameter region.
