Modified <i> f(R)</i> Gravity and Thermodynamics of Time-Dependent Wormholes at Event Horizon

Abstract

In the context of modified ( ) f R gravity theory, we study time-dependent wormhole spacetimes in the radiation background. In this framework, we attempt to generalize the thermodynamic properties of time-dependent wormholes in ( ) f R gravity. Finally, at event horizon, the rate of change of total entropy has been discussed.
