[ 1 ] - گذار از مرز فانتوم با جفتیدگی ناکمینه جنبشی و گاؤس- بانه

In this paper we study a dark energy model in which tachyon scalar field non-minimally coupled with kinetic energy and Gauss-Bonnet invariant. Energy density рø, pressure рø and scalar field equation of motion have been calculated and then equation of state parameter has been extracted. We have investigated the conditions required for ω=-1 crossing in such a model. It is shown that phantom divi...
