Double ramification cycles on the moduli spaces of curves
F. Janda, R. Pandharipande, A. Pixton +1
Curves of genus g which admit a map to CP1 with specified ramification profile mu over 0 and nu over infinity define a double ramification cycle DR_g(mu,nu) on the moduli space of…

Pixton's double ramification cycle relations
Emily Clader, Felix Janda
We prove a conjecture of Pixton, namely that his proposed formula for the double ramification cycle on Mbar_{g,n} vanishes in codimension beyond g. This yields a collection of taut…
