Universal Thermodynamics with state finder parameters: A general prescription
Abstract
The work deals with universal thermodynamics for flat FRW model, considering interacting n-fluid system. By introducing the state finder parameters, the feasible regions in the \r,s\-plane has been examined for the validity of the Generalized Second Law of Thermodynamics. A general prescription for the evolution of the horizon has been derived for general non-static spherically symmetric space time and then it is applied to FRW universe. A general restriction on the matter has been found for the validity of GSLT.
