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

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/118188We 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.Differential Geometry53C42A Generalized Maximum Principle for Yau's Square Operator, with Applications to the Steady State Spacetext
