On the constraint equations in Einstein-aether theories and the weak
gravitational field limit    [PDF]

David Garfinkle, James Isenberg, Jose M. Martin-Garcia

We discuss the set of constraints for Einstein-aether theories, comparing the flat background case with what is expected when the gravitational fields are dynamic. We note potential pathologies occurring in the weak gravitational field limit for some of the Einstein-aether theories.
