AI 中文摘要

本文在ℓ²中一类具有任意(可能无限)余维的曲面上给出了曲面测度的显式构造,这些测度由与固定高斯乘积测度相关的局部表示构造而成。随后建立了局部和整体的高斯-格林型公式,引入了最高次微分形式的概念,并推导了相关的斯托克斯型恒等式,还确定了由曲面定向诱导的边界定向。此外,本文研究了ℱ-连续性与博雷尔可测性之间的关系,揭示了无限维环境下特有的现象。

英文摘要

In this paper, we give an explicit construction of surface measures on a class of surfaces with arbitrary, possibly infinite, codimension in $\ell^2$. These measures are constructed from local representations associated with a fixed Gaussian product measure. We then establish local and global Gauss--Green-type formulas, introduce a notion of top-degree differential form, and derive an associated Stokes-type identity. We also determine the orientation of the boundary induced by the orientation of the surface. Moreover, therelationship between $\mathcal F$-continuity and Borel measurability is examined,which reveals a phenomenon specific to the infinite-dimensional setting.
