Blaschke's problem for timelike surfaces in pseudo-Riemannian space forms
Peng Wang
We show that isothermic surfaces and S-Willmore surfaces are also the solutions to the corresponding Blaschke's problem for both spacelike and timelike surfaces in pseudo-Riemannia…

Polar transform of Spacelike isothermic surfaces in 4-dimensional Lorentzian space forms
Xiang Ma, Peng Wang
The conformal geometry of spacelike surfaces in 4-dimensional Lorentzian space forms has been studied by the authors in a previous paper, where the so-called polar transform was in…
