Lie, Noether, Kosmann, and Diffeomorphism Anomalies Redux
Taeyeon Kim, Piljin Yi
The Noether procedure carries an inherent ambiguity due to the necessary local extension, no longer a symmetry, of the global symmetry. The gauging should fix the ambiguity once an…

Discrete Gauge Anomalies and Instantons
Qiang Jia, Piljin Yi
We revisit anomalous phases related to large gauge transformations, such as the Witten anomaly. The latter, known to plague theories, is well-understood in terms of $…

Axial Anomalies of Maximally Supersymmetric Tensor Theories
Piljin Yi, Yi Zhang
We revisit anomalies of and maximally supersymmetric tensor theories in . A on-shell tensor multiplet descends to that of the maximal supergravit…
