Hi,

I'm a graduate student in physics, as such I'm often required to crunch large symbolic integrals. I was wondering if there is an easy way to tell Mathematica that a certain variable is real and positive and the like. I can use a>0; to do positive, but defining it as real would be helpful so that some of the longer integrals don't run through so many assumption algorithms and wouldn't take so long to process and I wouldn't have to weed through lengthy lists of assumptions to find my eventual output.

Cheers for any information,

Zach
