Abstract
We show that non-stationary Gromov–Witten invariants of P1 can be extracted from open periods of the Eynard–Orantin topological recursion correlators ωg,n whose Laurent series expansion at ∞ compute the stationary invariants. To do so, we overcome the technical difficulties to global loop equations for the spectral x(z) = z + 1/z and y(z) = ln z from the local loop equations satisfied by the ωg,n, and check these global loop equations are equivalent to the Virasoro constraints that are known to govern the full Gromov–Witten theory of P1.
