| Jan 3, 2010 at 21:12 | comment | added | David Ben-Zvi | In a formal sense -- the extension to nodal curves is the algebraic geometer's response to gluing pairs of pants in CFT.. in the DAG picture you can glue pairs of pants/ cut and paste surfaces, which is formally equivalent to degenerating to a nodal curve and deforming away in the Gromov-Witten picture.. | |
| Dec 26, 2009 at 9:26 | comment | added | Kevin H. Lin | Another question: Does the DAG picture allow for nodal surfaces (stable curves/maps)? | |
| Dec 14, 2009 at 21:42 | comment | added | David Ben-Zvi | - to elaborate, higher genus GW is the "volume" of the moduli of stable maps to X, defined using virtual fundamental classes; higher genus B-model is the "volume" of the derived scheme of maps from Sigma, defined using the Calabi-Yau form.. seems directly analogous, no? | |
| Dec 14, 2009 at 21:35 | comment | added | David Ben-Zvi | I don't understand your comment - in what sense is it less standalone than say the definition of higher genus GW invariants? | |
