希尔伯特空间中非高斯可微测度和曲面测度的马利亚文演算

Malliavin Calculus for non Gaussian differentiable measures and surface measures in Hilbert spaces

Giuseppe Da Prato, Alessandra Lunardi, Luciano Tubaro

摘要:

我们在一个具有概率测度$ν$的Hilbert空间中构造曲面测度.该理论适用于Burgers和反应扩散方程等随机偏微分方程的不变测度。其他例子是加权高斯测度和非高斯测度的特殊积测度$ν$;在这种情况下,我们展示了一个以$ν$为不变测度的马尔可夫过程。在任何情况下,我们证明了分部积分法公式的子级集的好功能(包括领域和超平面),涉及表面积分。

英文摘要:

We construct surface measures in a Hilbert space endowed with a probability measure $ν$. The theory fits for invariant measures of some stochastic partial differential equations such as Burgers and reaction--diffusion equations. Other examples are weighted Gaussian measures and special product measures $ν$ of non Gaussian measures; in this case we exhibit a Markov process having $ν$ as invariant measure. In any case we prove integration by parts formulae on sublevel sets of good functions (including spheres and hyperplanes) that involve surface integrals.
