Description
1) General "definition" of topological phases and of invertible phases.
2) Illustration of invertible phases with a 1+1d Majorana chain and connection to continuum field theory (massive Majorana fermion).
3) Introduction of bordism invariance and classification of invertible phases.
4) If time allows, invertible phases with Z classification (Chern simons response) as illustrated by 2+1d p+ip superconductor.
5) Phases protected by symmetry. Symmetry on the lattice.
6) In cohomology SPT and Dijkgraaf-Witten theories. If time allows, a detailed analysis of the 2+1D Levin-Gu bosonic Z 2 SPT.
