A Generalized Maximum Principle for Yau's Square Operator, with Applications to the Steady State Space

الأصل · EN

We derive, for the square operator of Yau, an analogue of the Omori-Yau maximum principle for the Laplacian. We then apply it to obtain nonexistence results concerning complete spacelike hypersurfaces with constant higher order mean curvature in the Steady State space.
