WebApr 15, 2007 · In general relativity, the energy conditions are invoked to restrict general energy-momentum tensors T{sub {mu}}{sub {nu}} in different frameworks, and to derive general results that hold in a variety of general contexts on physical grounds. WebThe strong energy condition (SEC) requires that Y ≡ ρ+ pr + 2p⊥ ≥ 0. Meanwhile, in the static region T k k − T t t = Y and we see from ( 8 ), ( 9) that in each of static regions in our system ∫ dur2Y < 0, except from the outer one.
