Hi everybody, I have heard that a program for solving integrals goes around under the same name as the well known book of Gradshteyn and Ryzhik. I have heard it is quite powerful. Anyone have any idea where I can find it?

Thanks a lot guys. I have done some reading and some serious thinking on these issues. I'm still pretty freaked out by the fact that I start with an integral that is clearly diverging, I employ a correct STRICTLY MATHEMATICAL procedure and I end up with a finite answer. This seems to be the case...

Hi guys, this is my first post. I recently realized that there is something odd going on with dimensional regularization so I figured I could ask here. So let's take equation (A.44) in Peskin's book. Now if we set n=1 and d=3-e, this integral is obviously ultraviolet diverging(in fact...
