We also classify non-Ricci-flat κ-noncollapsed cohomogeneity one steady gradient Ricci solitons in dimension four and five. After passing to a finite cover, in dimension four, they must be the Bryant soliton or Appleton's noncollapsed 4d steady soliton; in dimension five, they must be the Bryant soliton or solitons constructed by Ivey–Dancer–Wang.Ricci solitonsAncient solutionsRicci-flat & Calabi–Yau(Non)collapsing4-manifoldsHomogeneous spacesStability & uniqueness
