@Anixx: I am pretty sure that fedja is a world class classical analyst. If he has never heard of the polygamma function, perhaps you should rethink your position and be willing to define terms that are unfamiliar to people who might give answers to your questions.
The polygamma function is found neither in the index of Special Functions by Andrews, Askey and Roy, nor in Whittaker and Watson, although the digamma function is in both (as "logarithmic derivate of Gamma function" in the latter).
Dan, not that I consider it important, but I was interested in seeing whether I would get the same results you got. If I enter "polygamma function" with quotes into Google, I get a little over 11000 hits; if I enter "compact closed category" with quotes, I get more than 25000. If I enter polygamma function without quotes, I get between 27000 and 28000 hits; if I try the same for compact closed category, I get over 43000000 hits.
I agree with your point, Gerry. I cast a vote to close.
@dan: In order to understand a question about "compact closed categories" I would have to ask what they are. So, yes, the definition (or link to it) should be included in that question as well.
