关于希尔伯特空间值扩散过程的存在性定理

On the Existence Theory of Hilbert Space valued Diffusion Processes

Günter Hinrichs

摘要:

证明了希尔伯特空间中某些线性随机微分方程的解,即算子有界算子的线性随机微分方程和保守的随机薛定谔方程的解,可以通过将方程分成"确定性“和"“随机”部分,并以迭代的方式将相应的解流交替地应用于初始值。

英文摘要:

We prove that the solution of certain linear stochastic differential equations in Hilbert spaces, namely those with bounded operators as well as the conservative stochastic Schrödinger equations, can be obtained - along the lines of the Lie-Trotter product formula from semigroup theory - by splitting the equation into a ``deterministic'' and a ``stochastic'' part and alternately applying the corresponding solution flows in an iterative manner to the initial value.
