Crepant Transformation Conjecture For the Grassmannian Flop

Algebraic Geometry 2025-04-08 v2

Abstract

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 to degree-2 classes, and then deduces the general result using ``explicit reconstruction'' (also known as the method of big I-functions).
