I'm slowly understanding quantum field theory. I believe I understand non-interacting quantum fields pretty well, I would say as a formalism for real signal analysis, and their relationship to classical random fields, but the mathematics and understanding of interacting quantum fields is harder.

As a manifesto for PhysicsSE, I would say that research in Physics is a cooperative endeavour, in which productive failures are sometimes better for us than apparent successes. Sometimes seeing what is productive takes the ingenuity of many people and many years.

comment Bessel function integral and Mellin transform
I read G&R as allowing $\nu$ to be any complex number. G&R is pretty careful about listing the constraints, so if it says nothing about a parameter, it can be anything that makes sense for the definition of the function. $\gamma$ must be real and positive-definite; $\alpha,\beta$ may be complex, with the real part positive-definite.

Thanks. I worried that I would get downvotes by association for posting this, but I wanted to check that it was bad, bad, bad, and to bring it to MathSE's attention if it was. The arXiv blog's daily choices have been getting steadily less interesting by my estimation.

Excellent, thanks.
