We have decided to discontinue the publication of preprints on our preprint server as of 1 March 2024. The publication culture within mathematics has changed so much due to the rise of repositories such as ArXiV (www.arxiv.org) that we are encouraging all institute members to make their preprints available there. An institute's repository in its previous form is, therefore, unnecessary. The preprints published to date will remain available here, but we will not add any new preprints here.
Parameterized Gromov-Witten invariant and topology of symplectomorphism groups
Hông Vân Lê and Kaoru Ono
In this note we study the topology of symplectomorphismgroups using symplectic bundle and Gromov-Witten invariant. As application we show the non-triviality of certain homotopy groups of some symplectomorphismgroups.
