| Jul 25, 2010 at 21:29 | comment | added | Kevin H. Lin | Thanks, Damien. By the way, Lurie has a new paper that is probably relevant to this discussion: math.harvard.edu/~lurie/papers/moduli.pdf | |
| Jul 24, 2010 at 19:06 | comment | added | DamienC | I would advise you to take a look at Marco Manetti's paper "Extended deformation functors" (IMRN) or "Deformation theory via differential graded Lie algebras" (math.AG/0507284). Another excellent reference (but difficult to read, at least for me) is of course DAG-IV by Jacob Lurie : math.harvard.edu/~lurie/papers/DAG-IV.pdf | |
| Jul 22, 2010 at 7:28 | comment | added | Kevin H. Lin | Do you know any references that talk about "derived" deformations? Is any of this written up anywhere yet? | |
| Jul 16, 2010 at 20:57 | comment | added | DamienC | Yes, exactly! :-) | |
| Jul 14, 2010 at 23:10 | comment | added | Kevin H. Lin | Oh, I see. We have $m_n : V^{\otimes n} \to V[2-n]$, which has "Hochschild degree" $n$ but "homological degree" $2-n$, hence total degree $n+2-n = 2$. | |
| Jul 14, 2010 at 22:41 | comment | added | Kevin H. Lin | How can I view the "Taylor coefficients" or structure maps $m_n$ of an $A_\infty$ algebra as elements of the Hochschild cochain complex? | |
