I am doing some Cauchy integration and in some intermediate steps I have something that looks like that:
\epsilon is very small and positive. For my purpose I am only concerned with the sign in front of the
Now my question is: How can I tell Mathematica to substitute the
I*\epsilon(k1-p1)/k1 term by
k1>0 .I tried using replace (/.) but it does not do anything. I would very much appreciate any help or insight since this situation shows up many times in what I am currently doing.
