Abstract

We show that non-stationary Gromov-Witten invariants of P1\mathbb{P}^1 can be extracted from open periods of the Eynard-Orantin topological recursion correlators ωg,n\omega_{g,n} whose Laurent series expansion at \infty compute the stationary invariants. To do so, we overcome the technical difficulties to global loop equations for the spectral x(z)=z+1/zx(z) = z + 1/z and y(z)=lnzy(z) = \ln z from the local loop equations satisfied by the ωg,n\omega_{g,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\mathbb{P}^1.
