Almgren-Pitts与Allen-Cahn极小极大理论的比较

A comparison of the Almgren-Pitts and the Allen-Cahn min-max theory

Akashdeep Dey

AI总结:

本文证明Allen-Cahn宽度与Almgren-Pitts宽度相等,且两种极小极大理论生成的闭极小超曲面一致,同时建立了二者指数上界的关联。

摘要:

Allen-Cahn方程的极小极大理论由Guaraco与Gaspar-Guaraco建立,他们证明Allen-Cahn宽度大于或等于Almgren-Pitts宽度。本文将证明反向不等式同样成立,即Allen-Cahn宽度小于或等于Almgren-Pitts宽度,因此二者宽度完全相等。本文还将证明,所有通过Allen-Cahn极小极大理论得到的闭极小超曲面(具备最优正则性),同样可由Almgren-Pitts极小极大理论生成。作为推论,本文指出由Marques-Neves和Li证明的Almgren-Pitts框架下的指数上界,也可通过Gaspar和Hiesmayr证明的Allen-Cahn框架下的指数上界得到。

英文摘要:

Min-max theory for the Allen-Cahn equation was developed by Guaraco and Gaspar-Guaraco. They showed that the Allen-Cahn widths are greater than or equal to the Almgren-Pitts widths. In this article we will prove that the reverse inequalities also hold i.e. the Allen-Cahn widths are less than or equal to the Almgren-Pitts widths. Hence, the Almgren-Pitts widths and the Allen-Cahn widths coincide. We will also show that all the closed minimal hypersurfaces (with optimal regularity) which are obtained from the Allen-Cahn min-max theory are also produced by the Almgren-Pitts min-max theory. As a consequence, we will point out that the index upper bound in the Almgren-Pitts setting, proved by Marques-Neves and Li, can also be obtained from the index upper bound in the Allen-Cahn setting, proved by Gaspar and Hiesmayr.
