Alberto Maione, Andrea Pinamonti, Francesco Serra Cassano

摘要:

给定$\mathbb{R}^n$上的一类局部Lipschitz向量场$X(x)=(X_1(x),\dots,X_m(x))$,$m\leq n$,研究了依赖于$X$的积分泛函.利用\cite{MPSC1}中的结果,我们研究了这些泛函的极小、极小元和动量的收敛性。此外,我们将这些结果应用于Carnot群中的周期均匀化,并证明了依赖于$X$的二阶线性微分算子的$H$ -紧性定理。

英文摘要:

Given a family of locally Lipschitz vector fields $X(x)=(X_1(x),\dots,X_m(x))$ on $\mathbb{R}^n$, $m\leq n$, we study integral functionals depending on $X$. Using the results in \cite{MPSC1}, we study the convergence of minima, minimizers and momenta of those functionals. Moreover, we apply these results to the periodic homogenization in Carnot groups and to prove a $H$-compactness theorem for linear differential operators of the second order depending on $X$.
