Abstract

We derive some restrictions on the topology of a monotone Lagrangian submanifold LCnL\subset\mathbf{C}^n by making observations about the topology of the moduli space of Maslov 2 holomorphic discs with boundary on LL and then using Damian's theorem which gives conditions under which the evaluation map from this moduli space to LL has nonzero degree. In particular we prove that an orientable 3-manifold admits a monotone Lagrangian embedding in C3\mathbf{C}^3 only if it is a product, which is a variation on a theorem of Fukaya. Finally we prove an h-principle for monotone Lagrangian immersions.
