Crepant Transformation Conjecture For the Grassmannian Flop
Wendelin Lutz, Qaasim Shafi, Rachel Webb
We prove an explicit form of the Crepant Transformation Conjecture for Grassmannian flops. Our approach uses abelianization to first relate the restrictions of the Lagrangian cones…

Reflexive polygons and rational elliptic surfaces
Antonella Grassi, Giulia Gugiatti, Wendelin Lutz +1
In this note we study in detail the geometry of eight rational elliptic surfaces naturally associated to the sixteen reflexive polygons. The elliptic fibrations supported by these…

The Abelian/non-Abelian Correspondence and Gromov-Witten Invariants of Blow-ups
Tom Coates, Wendelin Lutz, Qaasim Shafi
We prove the Abelian/non-Abelian Correspondence with bundles for target spaces that are partial flag bundles, combining and generalising results by Ciocan-Fontanine-Kim-Sabbah, Bro…
