Anomaly inflow and -form gauge theories
Chang-Tse Hsieh, Yuji Tachikawa, Kazuya Yonekura
Chiral and non-chiral -form gauge fields have gravitational anomalies and anomalies of Green-Schwarz type. This means that they are most naturally realized as the boundary modes…

Anderson duality of topological modular forms and its differential-geometric manifestations
Yuji Tachikawa, Mayuko Yamashita
We construct and study a morphism of spectra implementing the Anderson duality of topological modular forms (). Its differential version will then be introduced, allo…

N=2 supersymmetric dynamics for pedestrians
Yuji Tachikawa
We give a pedagogical introduction to the dynamics of N=2 supersymmetric systems in four dimensions. The topic ranges from the Lagrangian and the Seiberg-Witten solutions of SU(2)…
