Mar 3, 2018 at 23:31 comment added Michael Albanese If it were scalar flat it would be Ricci-flat (Bourguignon's result), and because it is three-dimensional, it would also be flat.
Mar 3, 2018 at 21:54 comment added Ryan Unger The example for $n=3$ is nice. Why doesn't it admit a scalar flat metric though? Do you know about $n\ge 5$?
