    Surfaces in S3 of L1-2-type
    (Springer, 2018) Lucas Saorín, Pascual; Ramírez-Ospina, Héctor Fabián; Matemáticas
    In this paper we show that an L_1-2-type surface M in S^3 is either an open portion of a standard Riemannian product S^1(a) x S^1(b), of any radii, or it has non constant mean curvature H, non constant Gaussian curvature K, and non constant principal curvatures k1 and k2.
