紧流形上Feynman路径积分的时间切片逼近

Time-slicing approximation of Feynman path integrals on compact manifolds

Shota Fukushima

摘要:

利用Feynman路径积分的时间切片近似,构造了紧致流形上含时薛定谔方程的基本解.证明了在Sobolev空间到平方可积函数空间的一致算子拓扑中,短时近似解的迭代收敛于标量曲率修正的薛定谔方程的基本解.为了用我们的方法构造时间切片近似,我们只需要考虑由足够短的经典路径组成的断裂路径。通过证明短时近似解的两个重要性质,即稳定性和相容性,证明了基本解的收敛性。

英文摘要:

We construct fundamental solutions to the time-dependent Schrödinger equations on compact manifolds by the time-slicing approximation of the Feynman path integral. We show that the iteration of short-time approximate solutions converges to the fundamental solutions to the Schrödinger equations modified by the scalar curvature in the uniform operator topology from the Sobolev space to the space of square integrable functions. In order to construct the time-slicing approximation by our method, we only need to consider broken paths consisting of sufficiently short classical paths. We prove the convergence to fundamental solutions by proving two important properties of the short-time approximate solution, the stability and the consistency.
