证明了维数大于2的不相容域的几何刚性不等式。在超临界状态下,我们能够得到强的标度不变的L^p估计,而对于临界指数1 ^* = frac{n}{n-1}$,我们只对弱-L^1 $范数有标度不变的不等式。虽然不是最优的,这样的估计在$L^{1,infty}$是足够的,以推断出一个有用的引理,给出$BV$界的$SO(n)$-值域有界卷曲。
We prove geometric rigidity inequalities for incompatible fields in dimension higher than 2. We are able to obtain strong scaling-invariant $L^p$ estimates in the supercritical regime, while for critical exponent $1^* = frac{n}{n-1}$ we have a scaling invariant inequality only for the weak-$L^1$ norm. Although not optimal, such an estimate in $L^{1 ,infty}$ is enough in order to infer a useful lemma which gives $BV$ bounds for $SO(n)$-valued fields with bounded Curl.
