Killing Fields on Compact m-Quasi-Einstein Manifolds

Abstract: We show that given a compact, connected $m$-quasi Einstein manifold $(M,g,X)$ without boundary, the potential vector field $X$ is Killing if and only if $(M, g)$ has constant scalar curvature. This extends a result of Bahuaud-Gunasekaran-Kunduri-Woolgar, where it is shown that $X$ is Killing if $X$ is incompressible. We also provide a sufficient condition for a compact, non-gradient $m$-quasi Einstein metric to admit a Killing field. We do this by following a technique of Dunajski and Lucietti, who prove that a Killing field always exists in this case when $m=2$. This condition provides an alternate proof of the aforementioned result of Bahuaud-Gunasekaran-Kunduri-Woolgar. This alternate proof works in the $m = -2$ case as well, which was not covered in the original proof.

Don't know much about the details, but it seems like Boeing's problem is that they tried to do cost cutting stunts like the grown-ass scammers in digital tech but forgot that their line of business takes safety seriously and that the public won't just accept doors falling off airplanes with a shrug, humbly accepting that even billionaire geniuses cannot prevent everything.
