AI总结:

本文在Heisenberg群中研究具有水平Sobolev正则性的接触向量场的传输和连续性方程的适定性,通过适应平滑策略实现了首次在亚黎曼几何设置中的适定性结果。

摘要:

在本文中,我们获得了在Heisenberg群$\mathbb{H}^n$中对于一类接触向量场$\mathbf b$的传输和连续性方程的适定性,这些向量场的正则性假设自然且未被经典的欧几里得理论[18]所覆盖。这是首次在真正的亚黎曼几何设置中获得适定性的例子,我们通过将[18]中的平滑策略适应到$\mathbb{H}^n$几何中来实现这一点。在本文的最后部分,我们说明了我们的结果未被第一作者在[1]中解决的欧几里得$BV$情况所覆盖,并将其与基于Bakry-Émery方法的插值和对称导数积分表示的[7]策略进行了比较。

英文摘要:

In this paper we obtain the well-posedness of the transport and continuity equations in the Heisenberg groups $\mathbb{H}^n$ for a class of contact vector fields $\mathbf b$, under natural assumptions on the regularity of $\mathbf b$ not covered by the, now classical, Euclidean theory [18]. It is the first example of well-posedness in a genuine sub-Riemannian setting, that we obtain adapting to the $\mathbb{H}^n$ geometry the mollification strategy of [18]. In the final part of the paper we illustrate why our result is not covered by the Euclidean $BV$ case solved by the first author in [1], and we compare it with the strategy of [7], based on the representation of the commutator by interpolation à la Bakry-Émery and an integral representation of the symmetrized derivative of $\mathbf b$.
