Conformal vector fields, curvature and Ricci collineations are studied. Many implications for existence of these symmetries on generalized Robertson-Walker spacetimes are obtained. Finally, Ricci solitons on generalized Robertson-Walker spacetimes admitting conformal vector fields are investigated.en-USUniversity for GEOMETRYRIGIDITYMANIFOLDSVECTOR-FIELDSCONFORMAL VECTOR-FIELDSRicci solitonRobertson-Walker spacetimescollineationsconcircular vector fieldsConformal vector fields53C5053C2153C25On symmetries of generalized Robertson-Walker spacetimes and applicationsArticlehttps://doi.org/10.1080/1726037X.2017.1323418
