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…

The equivalence problem for generic four-dimensional metrics with two commuting Killing vectors
D. Catalano Ferraioli, M. Marvan
We consider the equivalence problem of four-dimensional semi-Riemannian metrics with the -dimensional Abelian Killing algebra. In the generic case we determine a semi-invariant…
