Deligne products of line bundles over moduli spaces of curves

L. Weng, D. Zagier

Research output: Contribution to journalArticlepeer-review


We study Deligne products for forgetful maps between moduli spaces of marked curves by offering a closed formula for tautological line bundles associated to marked points. In particular, we show that the Deligne products for line bundles on the total spaces corresponding to "forgotten" marked points are positive integral multiples of the Weil-Petersson bundles on the base moduli spaces.
