Feynman路径积分在$L^p$中的收敛性

Convergence in $L^p$ for Feynman path integrals

Fabio Nicola

摘要:

本文考虑一类具有含时光滑磁势和电势的薛定谔方程,它们在无穷远处分别至多线性增长和二次增长。研究了相应的Feynman路径积分的时间切片近似在损失导数的$L^p$($1<p<\infty$)中的收敛性.结果是完全尖锐的,并保持很长一段时间,其中没有平滑效果。该技术基于相空间中关于某些波包的函数和算子的分解和重构。

英文摘要:

We consider a class of Schrodinger equations with time-dependent smooth magnetic and electric potentials having a growth at infinity at most linear and quadratic, respectively. We study the convergence in $L^p$ with loss of derivatives, $1<p<\infty$, of the time slicing approximations of the corresponding Feynman path integral. The results are completely sharp and hold for long time, where no smoothing effect is available. The techniques are based on the decomposition and reconstruction of functions and operators with respect to certain wave packets in phase space.
