Geometric and analytic results for Einstein solitons
Enrique Fernando López Agila, José Nazareno Vieira Gomes
We compute a lower bound for the scalar curvature of a gradient Einstein soliton under a certain assumption on its potential function. We establish an asymptotic behavior of the po…
Eigenvalue estimates for a class of elliptic differential operators in divergence form on Riemannian manifolds isometrically immersed in Euclidean space
Marcio C. Araújo Filho, José N. V. Gomes
In this paper, we obtain eigenvalue estimates for a larger class of elliptic differential operators in divergence form on a bounded domain in a complete Riemannian manifold isometr…
Compact gradient Einstein-type manifolds with boundary
Allan George de Carvalho Freitas, José Nazareno Vieira Gomes
We deal with rigidity results for compact gradient Einstein-type manifolds with nonempty boundaries. As a result, we obtain new characterizations for hemispheres and geodesic balls…
On Ricci almost solitons arising from conformal vector fields
Jose N. V. Gomes, Joao F. B. Pereira, Dragomir M. Tsonev
Let be a semi-Riemannian manifold of constant sectional curvature, and endowed with a conformal vector field . Consider a Riemannian manifold , isometrica…
