Framed motivic Donaldson-Thomas invariants of small crepant resolutions

Algebraic Geometry 2021-02-17 v2

Abstract

For an arbitrary integer r1r\geq 1, we compute rr-framed motivic PT and DT invariants of small crepant resolutions of toric Calabi-Yau 33-folds, establishing a "higher rank" version of the motivic DT/PT wall-crossing formula. This generalises the work of Morrison and Nagao. Our formulae, in particular their relationship with the r=1r=1 theory, fit nicely in the current development of higher rank refined DT invariants.
