On Certain Lagrangian Submanifolds of $S^{2} \times S^{2}$ and $C P^{n}$

Joel Oakley, Michael Usher

We consider various constructions of monotone Lagrangian submanifolds of $C P^{n}, S^{2} \times S^{2}$ , and quadric hypersurfaces of $C P^{n}$ . In $S^{2} \times S^{2}$ and $C P^{2}$ we show that s…

Michael Usher

For a class of Riemannian manifolds that include products of arbitrary compact manifolds with manifolds of nonpositive sectional curvature on the one hand, or with certain positive…
