We obtain new restrictions on Maslov classes of monotone Lagrangian submanifolds of ${ℂ}^n$. We also construct families of new examples of monotone Lagrangian submanifolds, which show that the restrictions on Maslov classes are sharp in certain cases.

单调拉格朗日子流形的球的乘积和连通和

我们对Maslov类的单调Lagrangian子流形获得了新的限制 ${ℂ}^{ñ}$。我们还构建了一系列新的单调拉格朗日子流形的实例，这表明在某些情况下对Maslov类的限制非常严格。
