Gravitational Descendants and Linearized Contact Homology
arXiv:1211.4808
Abstract
In this paper we prove a recursion relation between the the one-point genus-0 gravitational descendants of a Stein domain . This relation is best described by the degree -2 map in the linearized contact homology of , arising from the Bourgeois--Oancea exact sequence between symplectic homology of and linearized contact homology of . All one-point genus-0 gravitational descendants can be reduce to the one-point Gromov--Witten invariants via iterates of .
