| Feb 17, 2011 at 20:53 | comment | added | Ben Webster♦ | I believe pretty firmly that this is a duplicate of the cited question. I would vote to close on these grounds, if I weren't a moderator. Please direct discussion to tea.mathoverflow.net/discussion/963/… | |
| Feb 17, 2011 at 17:50 | comment | added | Theo Johnson-Freyd | Jan Weidner says that this is not intended to be an exact duplicate, but as written I don't see how mathoverflow.net/questions/1465/… is not more precise and answers the question asked here. So for now, I think this should be closed as duplicate. I would love to encourage more discussion of categorification, and so hope this question stays open; if it is going to, I ask that the question be precise-ified into something distinct from op. cit. | |
| Feb 17, 2011 at 17:16 | comment | added | Jan Weidner | I don't think, that this is an exact duplicate. For example Martins answer would not fit the other question, which asks for a categorification by complexes of graded vectorspaces. Also I would love to read Todds answer :) | |

| Feb 17, 2011 at 16:23 | comment | added | j.c. | The title of this question could be made more specific. | |
| Feb 17, 2011 at 15:22 | comment | added | Todd Trimble | I think I have to object to the closing of this question, maybe mainly because I was writing a long answer which attempts to say that there may be more to it than is suggested by how the equation was rewritten in the possible duplicate. Grrr... | |

exact duplicate | |
| Feb 17, 2011 at 14:03 | comment | added | Simon Wadsley | Incidentally, one could adapt the answers there by replacing $k[x]$ by $k[x]/(x^{n+1})$ to answer the second part. This seems less natural though. | |
| Feb 17, 2011 at 13:14 | comment | added | Simon Wadsley | First part was also asked (and answered) here mathoverflow.net/questions/1465/… | |
| Feb 17, 2011 at 11:48 | comment | added | Jan Weidner | I don't know, categorification is no precisely defined thing in my mind. Qiaochus answer contains a possible definition. However I also like Martins example very much, which does not fall under Qiaochus definition. Other possibilities would be to associate to graded things their "Hilbert polynomial" etc. | |

| Feb 17, 2011 at 11:15 | comment | added | Harry Gindi | In particular, could you explain what you mean by a "categorification" of a rational function/power series? | |
| Feb 17, 2011 at 11:08 | comment | added | Harry Gindi | Come on, you've asked questions on MO before. What is this supposed to be? Please fix it. | |
