Refined BPS numbers on compact Calabi-Yau threefolds from Wilson loops
Min-xin Huang, Sheldon Katz, Albrecht Klemm +1
We relate the counting of refined BPS numbers on compact elliptically fibred Calabi-Yau threefolds to Wilson loop expectations values in the gauge theories that emerge in vario…

D-critical locus structure on the Hilbert schemes of some local toric Calabi-Yau threefolds
Sheldon Katz, Yun Shi
The notion of a d-critical locus is an ingredient in the definition of motivic Donaldson-Thomas invariants by [BJM19]. In this paper we show that there is a d-critical locus struct…
