A class of quasilinear second order partial differential equations which describe spherical or pseudospherical surfaces
Diego Catalano Ferraioli, Tarcísio Castro Silva, Keti Tenenblat
Second order partial differential equations which describe spherical surfaces (ss) or pseudospherical surfaces (pss) are considered. These equations are equivalent to the structure…
A note on isometric immersions and differential equations which describe pseudospherical surfaces
Diego Catalano Ferraioli, Tarcísio Castro Silva, Keti Tenenblat
In this paper, we provide families of second order non-linear partial differential equations, describing pseudospherical surfaces (pss equations), with the property of having local…
Noncompact quasi-Einstein manifolds conformal to a Euclidean space
Ernani Ribeiro, Keti Tenenblat
The goal of this article is to investigate nontrivial -quasi-Einstein manifolds globally conformal to an -dimensional Euclidean space. By considering such manifolds, whose co…
