As a result, we show that any quadratic curvature functional admits different non-Einstein homogeneous critical metrics and that there exist homogeneous metrics which are critical for all quadratic curvature functionals without being Einstein PB Cambridge University Press SN 0308-2105 YR 2022 FD 2022 LK http://hdl.handle.net/10347/29282 UL http://hdl.handle.net/10347/29282 LA eng NO Brozos-Vázquez, M., Caeiro-Oliveira, S., & García-Río, E.
