Einstein hypersurfaces of and
Benedito Leandro, Romildo Pina, João Paulo dos Santos
In this paper, we classify the Einstein hypersurfaces of and . We use the characterization of the hypersurfaces of…
An analysis of symmetry groups of generalized -quasi-Einstein manifolds
Paula Correia, Benedito Leandro, Romildo Pina
In this paper emphasis is placed on how the behavior of the solutions of a PDE is affected by the geometry of the generalized -quasi-Einstein manifold, and vice versa. Consideri…
Quasi-Einstein manifolds with structure of warped product product
Paula Gonçalves Correia Bonfim, Romildo Pina
In this paper we prove that under certain conditions in a quasi Einstein semi Riemannian warped product the fiber is necessarily a Einstein manifold. We provide all the quasi Einst…
Gradient Estimates on Warped Product Gradient Almost Ricci Solitons
Willian Isao Tokura, Levi Adriano, Romildo Pina +1
In this paper, by slightly modifying Li-Yau's technique so that we can handle drifting Laplacians, we were able to find three different gradient estimates for the warping function,…
Properties of Complete Noncompact Warped Product Gradient Yamabe Solitons
Willian Isao Tokura, Levi Adriano, Romildo Pina +1
In this paper, we look for properties of gradient Yamabe solitons on top of warped product manifolds. Utilizing the maximum principle, we find lower bound estimates for both the po…
