Abstract |
|
We give some nontrivial relations in the tautological ring of ℳg. These are derived from some new geometric relations obtained by localization on the moduli of stable quotients, which was recently introduced by A. Marian, D. Oprea and R. Pandharipande. |
Keywords
tautological relations, moduli space, stable quotients
