Abstract
We show the existence of a deformation process of hypersurfaces from a product space \(\mathbb {M}_1\times \mathbb {R}\) into another product space \(\mathbb {M}_2\times \mathbb {R}\) such that the relation of the principal curvatures of the deformed hypersurfaces can be controlled in terms of the sectional curvatures or Ricci curvatures of \(\mathbb {M}_1\) and \(\mathbb {M}_2.\) In this way, we obtain barriers which are used for proving existence or non existence of hypersurfaces with prescribed curvatures in a general product space \(\mathbb {M}\times \mathbb {R}\).
