The product rule in \(\kappa ^*({\mathcal {M}}_{g,n}^{ct})\)

  • Iman SetayeshEmail author


We describe explicit formulas for the product rule in \(\kappa ^*({\mathcal {M}}_{g,n}^{ct})\).



I would like to thank M. Einollah Zade, M. Saghafian and E. Salavati for their collaboration in the proof of Theorem 22. I am also grateful to E. Eftekhary, F. Janda and R. Pandharipande for helpful comments on an earlier version of this paper. This work was partially done when the author visited the Institute for Mathematical Research (FIM) in Zurich and the result was first presented in a lecture in the Einstein series in Algebraic Geometry at Humboldt University supported by the Einstein Stiftung in Berlin. The author was partially supported by a Grant from IPM (no. 95510026).
