• Lorentz and Poincare symmetries
• Modified theories of gravity

We study the condition for the consistency of the Godel metric with the dynamical Chern-Simons modified gravity. It turns out to be that this compatibility can be achieved only if the cosmological constant is variable in the space. 2010 Published by Elsevier B.V.
