稳定余维一积分 varifold 在密度 $Q+1/2$ 的经典锥附近的结构

The Structure of Stable Codimension One Integral Varifolds near Classical Cones of Density $Q+1/2$

Paul Minter

AI总结:

本文证明了 $\mathcal{S}_Q$ 类稳定余维一积分 varifold 在由 $2Q+1$ 个半超平面组成的平稳积分锥附近的多值 $C^{1,α}$ 正则性定理,推广了先前 $Q=2$ 的工作,且无需对分支集施加先验尺寸限制即可排除密度间隙。

摘要:

对于每个正整数 $Q\in\mathbb{Z}_{\geq 2}$,我们证明了 $\mathcal{S}_Q$ 类中 varifold 的多值 $C^{1,α}$ 正则性定理,即稳定余维一平稳积分 $n$-varifold,其没有顶点密度 $<Q$ 的经典奇点,且充分接近由 $2Q+1$ 个(按重数计算)沿公共轴相交的半超平面组成的平稳积分锥。这一结果进一步加深了对作者与 N. Wickramasekera 在 \cite{minterwick} 中实现的 $\mathcal{S}_Q$ 中(可能分支的)varifold 奇点附近局部结构的理解,并将作者先前在 $Q=2$ 情形下的工作 \cite{minter-5-2} 推广至任意 $Q\in\mathbb{Z}_{\geq 2}$。与以往工作的一个显著区别在于,我们的方法无需对(密度 $Q$)分支集施加任何先验尺寸限制即可排除密度间隙。

英文摘要:

For each positive integer $Q\in\mathbb{Z}_{\geq 2}$, we prove a multi-valued $C^{1,α}$ regularity theorem for varifolds in the class $\mathcal{S}_Q$, i.e., stable codimension one stationary integral $n$-varifolds which have no classical singularities of vertex density $<Q$, which are sufficiently close to a stationary integral cone comprised of $2Q+1$ half-hyperplanes (counted with multiplicity) meeting along a common axis. Such a result furthers the understanding of the local structure about singularities in the (possibly branched) varifolds in $\mathcal{S}_Q$ achieved by the author and N.~Wickramasekera (\cite{minterwick}) and generalises the authors' previous work in the case $Q=2$ (\cite{minter-5-2}) to arbitrary $Q\in \mathbb{Z}_{\geq 2}$. One notable difference with previous works is that our methods do not need any a priori size restriction on the (density $Q$) branch set to rule out density gaps.
