3维阶2次黎曼结构中极小固有图的正则性

Regularity of minimal intrinsic graphs in 3 dimensional sub-Riemannian structures of step 2

Davide Barbieri, Giovanna Citti

摘要:

本文给出了一类包含非幂零李代数的向量场的非特征内在极小图的正则性的一个刻画。主要结果扩展了以前的海森堡群,使用类似的技术来处理非线性。这种更广泛的设置提供了一个更好的理解几何约束,连同特定工具的潜力的提升冻结程序和插值不等式的扩展。作为正则性的结果,得到了极小图的一个叶状结果。

英文摘要:

This work provides a characterization of the regularity of noncharacteristic intrinsic minimal graphs for a class of vector fields that includes non nilpotent Lie algebras as the one given by Euclidean motions of the plane. The main result extends a previous one on the Heisenberg group, using similar techniques to deal with nonlinearities. This wider setting provides a better understanding of geometric constraints, together with an extension of the potentialities of specific tools as the lifting-freezing procedure and interpolation inequalities. As a consequence of the regularity, a foliation result for minimal graphs is obtained.
