Open Gromov-Witten of (ℂP1, ℝP1) - the stationary sector

Résumé :
We describe a construction of primary and descendant invariants of maps from marked disks to ℂP1 with boundary going to ℝP1, and calculate them. We then describe generalizations.
If time permits we do some of the following:
-Describe the surprising equivariant theory.
-Describe high genus case.
-Describe the open GW/Hurwitz correspondence.

Based on joint work (to appear) with Buryak, Pandharipande and Zernik.
