Quasihomogeneous three-dimensional real analytic Lorentz metrics do not exist
Sorin Dumitrescu, Karin Melnick
We show that a germ of a real analytic Lorentz metric on which is locally homogeneous on an open set containing the origin in its closure is necessarily locally homogen…

Quasihomogeneous three-dimensional real analytic Lorentz metrics
Sorin Dumitrescu
We classify germs at the origin of real analytic Lorentz metrics on R^3 which are quasihomogeneous, in the sense that they are locally homogeneous on an open set containing the ori…
