In today's lecture I review some basic concepts and tools of many-body theory (symmetrization postulate for N-body states, Fock space and second quantization, Wick's theorem, particle-hole picture)  The treatment I give is standard, and may be found in any of the textbooks in the [[references|References]].

The lecture notes are {{:secondquantizationshorter.pdf|here.}}
