Thanks at all. I think the Suzuki-Trotter expansion finally solved the problem for me.

Thanks a lot. I totally forgot about that relation. Just one last question: Usually one defines the exponential of an operator with the help of the taylor series. Can one also use this definition and is it equal to the taylor exp.?

True, writing them as exponentials is reasonable. But I don't like to reverse this in the end, writing 1+\delta x = e^x Could you explain why writing them as exponentials is not correct?

Hey, I'm trying to do exercise I.2.1. from Zee's QFT in a nutshell but I ran into a problem. The exercise is to derive the QM path integral with a Hamiltonian of the form 1/2 m p^2 + V(q). In the textbook he shows the proof for a free hamiltonian. He gets to a point where he has (I left out...
