review text: The paper under review concerns with some topics from the geometry of generalized Robertson-Walker spacetimes of imperfect fluid type. Section 5 is devoted to a new curvature tensor field called \textit{semiconformal curvature tensor}. Section 6 studies Ricci-Yamabe solitons for which the unit time-like velocity vector field is torse-forming. The last two sections deal with eta-Ricci-Yamabe solitons and the some corresponding harmonicity properties.
