Closed strong spacelike curves, Fenchel theorem and Plateau problem in the 3-dimensional Minkowski space
Nan Ye, Xiang Ma
We generalize the Fenchel theorem for strong spacelike closed curves of index in the 3-dimensional Minkowski space, showing that the total curvature must be less than or equal…

The Fenchel-type inequality in the 3-dimensional Lorentz space and a Crofton formula
Nan Ye, Xiang Ma, Donghao Wang
We generalize the Fenchel theorem to strong spacelike (which means that the tangent vector and the curvature vector span a spacelike 2-plane at each point) closed curves with index…
