Cuspidal edges and generalized cuspidal edges in the Lorentz-Minkowski 3-space

T. Fukui, R. Kinoshita, D. Pei +2

It is well-known that every cuspidal edge in the Euclidean space E^3 cannot have a bounded mean curvature function. On the other hand, in the Lorentz-Minkowski space L^3, zero mean…

$S_{t}^{1} \times S_{s}^{1}$ -valued lightcone Gauss map of a Lorentzian surface in semi-Euclidean 4-space

Donghe Pei, Lingling Kong, Jianguo Sun +1

We define the notions of $S_{t}^{1} \times S_{s}^{1}$ -valued lightcone Gauss maps, lightcone pedal surface and Lorentzian lightcone height function of Lorentzian surface in semi-Euclidean 4…
