Simons formulas in complex space forms and product spaces

Dorel Fetcu, Stefano Nardulli

We compute Simons type equations for parallel mean curvature submanifolds in complex space forms N^n(c), with constant holomorphic sectional curvature c, and product spaces N^n(c)x…

Biconservative surfaces in $S^{2} \times R$ and $H^{2} \times R$

Dorel Fetcu

We find the explicit local equations of biconservative surfaces with non-constant mean curvature in $S^{2} \times R$ and $H^{2} \times R$ , when the grad…

The rigidity of biconservative surfaces in Sol3

Dorel Fetcu

We consider biconservative surfaces in Sol3, find their local equations, and then show that all biharmonic surfaces in this space are minimal.
