Perturbative Anomaly Inflow on Orbifolds
Hao Y. Zhang
We study perturbative anomaly inflow for effective theories supported on orbifold fixed loci of the internal geometry. Donnelly's equivariant APS theorem gives a fixed-point densit…

Frozen Generalized Symmetries
Mirjam Cvetič, Markus Dierigl, Ling Lin +2
M-theory frozen singularities are (locally) - or -type orbifold singularities with a background fractional -monodromy surrounding them. In this paper, we revisit such ba…

K-theoretic Global Symmetry in String-constructed QFT and T-duality
Hao Y. Zhang
We propose that generalized symmetries in some string-constructed QFTs are given by K-theory. We thus have \textit{even-form} and \textit{odd-form} symmetries determined by $K_N(\p…
