Characteristic numbers of rational curves with cusp or prescribed triple contact
Joachim Kock
This note pursues the techniques of modified psi classes on the stack of stable maps (cf. [Graber-Kock-Pandharipande]) to give concise solutions to the characteristic number proble…

Descendant invariants and characteristic numbers
Tom Graber, Joachim Kock, Rahul Pandharipande
On a stack of stable maps, the psi classes are modified by subtracting certain boundary divisors. These modified psi classes are compatible with forgetful morphisms, and are well-s…
