On Warped Product Gradient Ricci-Harmonic Soliton
Elismar Batista, Levi Adriano, Willian Tokura
In this paper we study gradient Ricci-Harmonic soliton with structure of warped product manifold. We obtain some triviality results for the potential function, warping function and…
Static Perfect Fluids With Symmetries
Marcelo Barboza, Willian Tokura, Levi Adriano
In this paper we utilize symmetries in order to exhibit exact solutions to Einstein's equation of a perfect fluid on a static manifold all of whose spatial factor belongs to the co…
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…
