Lorentzian approximations for a Lorentzian α-Sasakian manifold and Gauss-Bonnet theorems

Lorentzian approximations for a Lorentzian α-Sasakian manifold and Gauss-Bonnet theorems

In this paper, we define the Lorentzian approximations of a 3-dimensional Lorentzian α-Sasakian manifold. Moreover, we define the notions of the intrinsic curvature for regular curves, the intrinsic geodesic curvature of regular curves on Lorentzian surfaces and spacelike surfaces and the intrinsic...
