Abstract: 

Topic covered will include 

  • Derivation of chiral anomalies in two and four dimensions
  • The relation between anomalies and index theorems
  • Instantons and the theta vacuum
  • the strong OP problem and axions
  • ’t Hooft anomaly matching criterion
  • Chiral gauge theories
  • Anomalies on the lattice:  Ginsparg-Wilson fermions
  • Parity anomaly
  • Global anomalies
  • Domain wall fermions, the integer quantum hall effect, and topology in momentum space.
