齐次群中的Lipschitz向量场与Cauchy问题

On Lipschitz vector fields and the Cauchy problem in homogeneous groups

Valentino Magnani, Dario Trevisan

摘要:

我们引入一类齐次群中的“Lipschitz水平”向量场,我们给出了等价的描述,例如,在适当的导子方面。然后,我们研究了相关的柯西问题,提供了一个唯一性结果,在平衡点和向量场的对合子模的Lipschitz水平向量场。最后给出了Lipschitz水平向量场的一般适定性理论的一个反例,与欧氏理论相反。

英文摘要:

We introduce a class of "Lipschitz horizontal" vector fields in homogeneous groups, for which we show equivalent descriptions, e.g. in terms of suitable derivations. We then investigate the associated Cauchy problem, providing a uniqueness result both at equilibrium points and for vector fields of an involutive submodule of Lipschitz horizontal vector fields. We finally exhibit a counterexample to the general well-posedness theory for Lipschitz horizontal vector fields, in contrast with the Euclidean theory.
