Biconservative hypersurfaces with constant scalar curvature in space forms
Yu Fu, Min-Chun Hong, Dan Yang +1
Biconservative hypersurfaces are hypersurfaces which have conservative stress-energy tensor with respect to the bienergy, containing all minimal and constant mean curvature hypersu…

Minimal surfaces in a unit sphere pinched by intrinsic curvature and normal curvature
Dan Yang
We establish a nice orthonormal frame field on a closed surface minimally immersed in a unit sphere , under which the shape operators take very simple forms. Using this fram…
