Title

Ghost dark energy model in the presence of a linear, sign-changeable interaction

Pages

  763-774

Abstract

 In the present work we consider to generalized ghost dark energy in presence of a sign changeable interaction term. We obtain evolving cosmic parameters and plot them. We find a good agreement between the model and observations in primary analysis. The plots reveal that decreasing b, the universe enters acceleration phase earlier while decreasing ð  œ‰ leads a delay in enterance to the acceleration phase. Next we present a stability analysis according to squared sound speed and find that increasing the model can achieve positive domain for squared sound speed which shows signs of stability. Finaly we discuss the statefinder analysis and see the model can catch {r=1, s=0} at late time.
