Title |
Derived and modular resolutions of the Stable map moduli and applications |
Abstract |
In this talk, I will present a derived version of the resolutions of the moduli spaces of stable maps. This resolution can be used to rigorously define the so-called reduced GW numbers of CY threefolds (i.e., the GW numbers associated to the main components of the stable map moduli). The derived resolutions are singular (in the usual sense). For further applications, a resolution (in the usual sense) is desirable; I will describe how to achieve this by a sequence of modular blowups in the case of genera 1 and 2. |
