| Abstract |
We study compact maximal surfaces in the family of generalized\n Robertson-Walker spacetimes. We prove an integral inequality for their\n Gaussian curvature K, with equality characterizing the totally geodesic\n case. This gives an integral alternative to the irregular behaviour of\n K, which is due to the fact that the normal fibre bundle is Lorentzian\n and that our ambient spacetimes are not necessarily spatially\n homogeneous. We also give some consequences and applications for certain\n relevant cases of these spacetimes. |
