On Exceptional Times for Pointwise Convergence of Integral Kernels in Feynman–Trotter Path Integrals
On Exceptional Times for Pointwise Convergence of Integral Kernels in Feynman–Trotter Path Integrals
In the first part of the paper we provide a survey of recent results concerning the problem of pointwise convergence of integral kernels in Feynman path integrals, obtained by means of time-frequency analysis techniques. We then focus on exceptional times, where the previous results do not hold, and we show …
