Özet

We study Lagrangian submanifolds of the nearly Kahler S-3 x S-3 with respect to their so called angle functions. We show that if all angle functions are constant, then the submanifold is either totally geodesic or has constant sectional curvature and there is a classification theorem that follows from Dioos et al. (2018). Moreover, we show that if precisely one angle function is constant, then it must be equal to 0, pi/3 or 2 pi/3. Using then two remarkable constructions together with the classification of Lagrangian submanifolds of which the first component has nowhere maximal rank from, Bektas et al. (2018), we obtain a classification of such Lagrangian submanifolds. (C) 2018 Elsevier B.V. All rights reserved.
