DESCRIPTION:Speakers: Thomas Blomme (IMT)\n\nAbelian surfaces are complex 
 tori whose enumerative invariants seem to satisfy remarkable regularity pr
 operties. The computation of their reduced Gromov-Witten invariants has al
 ready achieved in the case of primitive classes (Bryan-Oberdieck-Pandharip
 ande-Yin). G. Oberdieck conjectured a few years ago a multiple cover formu
 la expressing in a very simple way the invariants for the non-primitive cl
 asses in terms of the primitive one. This would close the computation of G
 W invariants for abelian surfaces. In this talk\, we aim to explain the co
 njecture and how to prove most of it without being able to compute a Gromo
 v-Witten invariant. This is joint work in progress with Francesca Carocci.
