Gopakumar-Vafa invariants associated to singularities
Hao Zhang
This paper describes Gopakumar-Vafa (GV) invariants associated to singularities. We (1) generalize GV invariants to crepant partial resolutions of singularities, (2)…

Schubert defects in Lagrangian Grassmannians
W. Gu, L. Mihalcea, E. Sharpe +3
In this paper, we propose a construction of GLSM defects corresponding to Schubert cycles in Lagrangian Grassmannians, following recent work of Closset-Khlaif on Schubert cycles in…

5d SCFTs from Isolated Complete Intersection Singularities
Jisheng Mu, Yi-Nan Wang, Hao N. Zhang
In this paper, we explore the zoo of 5d superconformal field theories (SCFTs) constructed from M-theory on Isolated Complete Intersection Singularities (ICIS). We systematically in…
