Anisotropic power-law inflation

Abstract

We study an inflationary scenario in supergravity model with a gauge kinetic\nfunction. We find exact anisotropic power-law inflationary solutions when both\nthe potential function for an inflaton and the gauge kinetic function are\nexponential type. The dynamical system analysis tells us that the anisotropic\npower-law inflation is an attractor for a large parameter region.\n
