On Warped Product Gradient Yamabe Soliton
Willian I. Tokura, Levi Adriano, Romildo Pina
In this paper, we provide a necessary and sufficient conditions for the warped product to be a gradient Yamabe soliton when the base is conformal to an n-dimensiona…
Invariant Solutions for the Einstein Field Equation
Marcelo Barbosa, Benedito Leandro, Romildo Pina
In this paper we provide a method capable of producing an infinite number of solutions for Einstein's equation on static spacetimes with perfect fluid as a matter field. All spacet…
On the structure of Einstein warped product semi-Riemannian manifolds
Benedito Leandro, Márcio Lemes de Sousa, Romildo Pina
In this paper we consider a class of Einstein warped product semi-Riemannian manifolds with and . For with com…
Invariant Solutions for Gradient Ricci Almost Solitons
Tatiana Pires Bezerra Romildo Pina
In this paper we show that all conformal metrics to a pseudo-euclidean space invariant under the translation group, and all the conformal metrics product manifold also invariant by…
