thanks for the link and your Podcast with Markus V=F6lker.
To begin with, I object: the "verbosity" of the guest was IMHO excactly apropriate.
It was a very interesting journey through mathematica, and not only your special field, integration, but a wide range of fascinating topics and recent developments. Surely I will come back and listen again to some passages of the Podcast.
As you might remember, recently I found a bug in a special complex path integral (comp.soft-sys.math.mathematica) and, among others, you responded recognizing the bug.
In your podcast you made an important strategic remark: if there is a result given for an integral then it is correct, if Mathematica think the result might be incorrect, then no answer is given. I like this strategy, but, unfortunately, the newsgroup found a counter example. Different good looking results which are wrong.
Finally, may I ask you to give me a hint on some white paper on integration in Mathematica? I'd like to go into some more depth mainly on branch cuts of 2F1 etc.
Thanks in advance and best regards,
