We also investigate the necessary and sufficient conditions for a multiply generalized Robertson-Walker space-time and a generalized Reissner-Nordstrom space-time to be a gradient Ricci-harmonic soliton.eninfo:eu-repo/semantics/closedAccessGradient Ricci-harmonic solitonwarped productmultiply warped productArticle10.1142/S02198878215014012-s2.0-851077715229Q318WOS:000680851400003Q2
