The space $\mathbb R^n$ plays no role, you are just considering negative values of the variable. Also, if you really have a proof that there are no zeroes, then as you say the positivity follows immediately. Anyway, your question is answered by basic facts on hypergeometric functions such as Euler's integral representation (I give a version of that below). But since hypergeometric functions are not in general taught even to PhD students in mathematics, I do think the question is appropriate for MathOverflow. | |
