Abstract We study anisotropic inflation in non-minimal derivative coupling model where the scalar field non-minimally coupled to U(1) gauge fields and of Einstein tensor. Within framework we find power-law solutions this when both inflaton potential kinetic function are type high friction regime. show ratio anisotropy expansion rate is nearly constant, small proportional slow-roll parameters th...

In the framework of generalized Rastall theory (GRT), we study ability a non-minimal coupling between geometry and matter fields in order to provide setting, which allows for variable G during cosmic evolution. this regard, compatibility with Dirac hypothesis on variations is investigated, additionally, possibility obtaining current accelerated universe also addressed. summary, our indicates th...
