Factorization approach for barotropic FRW model with a cosmological constant

We apply the technique of standard supersymmetric factorization for any q factor ordering in the Wheeler–DeWitt (WDW) equation for barotropic Friedmann–Robertson–Walker (FRW) minisuperspace model, including the cosmological term. The resulting wave functions of the universe are exhibited as one-para...

Description
Summary:We apply the technique of standard supersymmetric factorization for any q factor ordering in the Wheeler–DeWitt (WDW) equation for barotropic Friedmann–Robertson–Walker (FRW) minisuperspace model, including the cosmological term. The resulting wave functions of the universe are exhibited as one-parameter families, which for particular values of the γ parameter of the barotropic model are exactly found.
