In particular we obtain asymptotically conical expanding Ricci solitons with positive scalar curvature on ℝ³ × S¹. More generally we construct continuous families of gradient expanding Ricci solitons on trivial vector bundles over products of Einstein manifolds with arbitrary Einstein constants.Ricci solitonsEinstein metricsRicci-flat & Calabi–Yau4-manifoldsScalar curvatureBoundaries & non-compact
