We study functions of bounded variation (and sets of finite perimeter) on a convex open set \({\varOmega }\subseteq X\), X being an infinite-dimensional separable real Hilbert space. We relate the total variation of such functions, defined through an integration by parts formula, to the short-time behaviour of the semigroup associated with a perturbation of the Ornstein–Uhlenbeck operator.

关于希尔伯特空间中凸域上的有界变化函数

我们研究凸开放集\({\ varOmega} \ subseteq X \)上的有界变化(和有限周长集)的函数,X是无限维可分离的实Hilbert空间。我们将这些函数的总变化(通过零件公式积分来定义)与半群的短时行为联系起来,该半群与Ornstein–Uhlenbeck算子的扰动有关。
