There should be a dedicated virtual fundamental class page describing its various constructions, such as from DAG, or as the virtual fundamental cycle in symplectic geometry.
Then the VFC is , hence it can be considered as a generalization of the fundamental class. (Although P^n could be replaced by a smooth ambient)
giving another VFC construction. Show this applied to mapping stacks
List out references to constructions of VFC
Note that 13/2 ways of counting curves gives the technical reasoning behind using excess intersections. Check out the appendix and look at the chern class . This is also in pages 9-10 of Thomas' original paper: https://arxiv.org/abs/math/9806111 — Preceding unsigned comment added by 71.196.136.221 ( talk) 18:40, 25 August 2022 (UTC)
