Asymptotic behavior of ω in general quintom model

  • Masoud Alimohammadi
Research Article

Abstract

For the quintom models with arbitrary potential \(V=V(\varphi, \sigma)\) , the asymptotic value of equation of state parameter ω is obtained by a new method. In this method, ω of stable attractors are calculated by using the ratio d ln V/d ln a in asymptotic region. All the known results, have been obtained by other methods, are reproduced by this method as specific examples.
