Topological Strings on Non-Commutative Resolutions

S Katz, A Klemm, T Schimannek, E Sharpe - … in Mathematical Physics, 2024 - Springer
In this paper we propose a definition of torsion refined Gopakumar–Vafa (GV) invariants for
Calabi–Yau threefolds with terminal nodal singularities that do not admit Kähler crepant …

Decomposition in Chern–Simons theories in three dimensions

T Pantev, E Sharpe - International Journal of Modern Physics A, 2022 - World Scientific
In this paper, we discuss decomposition in the context of three-dimensional Chern–Simons
theories. Specifically, we argue that a Chern–Simons theory with a gauged noneffectively …

Notes on two-dimensional pure supersymmetric gauge theories

W Gu, E Sharpe, H Zou - Journal of High Energy Physics, 2021 - Springer
A bstract In this note we study IR limits of pure two-dimensional supersymmetric gauge
theories with semisimple non-simply-connected gauge groups including SU (k)/ℤ k, SO …

Supersymmetric localization in GLSMs for supermanifolds

W Gu, H Zou - Journal of High Energy Physics, 2019 - Springer
A bstract In this paper we apply supersymmetric localization to study gauged linear sigma
models (GLSMs) describing supermanifold target spaces. We use the localization method to …

Low Dimensional Supersymmetric Gauge Theories and Mathematical Applications

H Zou - 2021 - vtechworks.lib.vt.edu
Abstract This thesis studies N=(2, 2) gauged linear sigma models (GLSMs) and three-
dimensional N= 2 Chern-Simons-matter theories and their mathematical applications. After a …
