| Feb 3, 2012 at 17:15 | comment | added | Vladimir Dotsenko | @Martin: while I too think that the "homological algebra" tag might be slightly misleading, Pierre-Yves is quite right saying that finding a presentation for an augmented algebra is intimately related to finding the first two levels of a resolution of the trivial module by free modules. I personally would think that "syzygies" or something alike would be the most instructive tag. | |
| Feb 3, 2012 at 16:24 | comment | added | Martin Brandenburg | Thank you for your obligingness. Is the relation you have written down for $n=3$ the only one coming from the $y_m$ or is this just an example? After all I could take any $3$-tuple of positive integers? | |

| Feb 3, 2012 at 14:07 | comment | added | Martin Brandenburg | PS: The homological-algebra tag is not appropriate because you don't resolve a module by free modules, but rather you want to resolve an algebra by free algebras aka find a presentation of it. | |
| Feb 3, 2012 at 14:05 | comment | added | Martin Brandenburg | 1) Can you give some specific examples for $y_m$? (because my first guess was that $I$ is generated by the $y_{ij}$ and I'm still not convinced of the contrary - I don't want to get through all these indices). 2) Have you tried the cases $n=2$ and $n=3$? | |
