Program:
- Introduction: string theory vs field theory
- Bosonic string: classical theory, symmetries, and constraints
- Bosonic string: old covariant quantization, light-cone quantization, BRST quantization
- Bosonic string: physical spectrum for open and closed strings
- Review of 2d conformal field theories and boundary conformal field theories.
- Bosonic string: physical spectrum, vertex operators
- Bosonic string: toroidal compactifications, T-duality, orbifolds, and D-branes
- Bosonic string: tree and one-loop amplitudes, effective actions and field-theory limit
- Consistent superstring theories in 10d: the RNS formalism, GSO projection, partition functions and modular invariance
- Supersymmetric strings: BRST quantization, picture changing and tree-level amplitudes
- Supersymmetric strings: low-energy effective theories and anomaly cancellation
- Supersymmetric strings: T-duality, S-duality, D-branes and their bound states
- (if time permits) Gauge and gravitational amplitudes from string theory (double copy, KLT, etc)
