• Resumen

  • Let W(z1,…,zn):(C∗)n→C be a Laurent polynomial in n variables, and let H be a generic smooth fiber of W. Ruddat et al. (Geom Topol 18:1343–1395, 2014) give a combinatorial recipe for a skeleton for H. In this paper, we show that for a suitable exact symplectic structure on H, the RSTZ-skeleton can be realized as the Liouville Lagrangian skeleton.
