Özet

In this paper, we find the necessary and sufficient conditions for a multiply warped product to be a gradient Ricci-harmonic soliton. We also investigate the necessary and sufficient conditions for a multiply generalized Robertson-Walker space-time and a generalized Reissner-Nordström space-time to be a gradient Ricci-harmonic soliton.
