We describe the g=0 stationary OGW theory of (CP1,RP1), including descendents and including equivariant invariants.

We find a very surprising formula for the intersection numbers in terms of sums over graphs, and based on it we are able to define by localization a whole-genus formula.

We conjecture that a true geometric definition that would yield the localization formula can be found.

If time permits I will define the open Hurwitz theory, and give a strong evidence for the correctness of the conjecture:

If it holds, then the all genus open GW/Hurwitz correspondence holds for (CP1,RP1).

Based on a joint work (to appear) with Alexandr Buryak, Rahul Pandharipande and Amitai Zernik.
