Abstract.

We show that any degree at least g monomial in descendant or tautological classes vanishes on ℳ g,n when g≥2. This generalizes a result of Looijenga and proves a version of Getzler’s conjecture. The method we use is the study of the relative Gromov-Witten invariants of ℙ1 relative to two points combined with the degeneration formulas of [IP1].
