Abstract

In this paper we consider Lorentzian surfaces in the 4-dimensional pseudo-Riemannian sphere S24(1)\mathbb S^4_2(1) with index 2 of curvature one. We obtain the complete classification of minimal Lorentzian surfaces S24(1)\mathbb S^4_2(1) whose Gaussian and normal curvatures are constants. We conclude that such surfaces have the Gaussian curvature 1/31/3 and the absolute value of normal curvature 2/32/3. We also give some explicit examples.
