General Relativity, Differential Forms and Einstein Lagrangian/Hamiltonian

Princeton University self-study undergraduate GR notes  [1973-1974]
by bob jantzen

These notes represented my then current understanding of curvature and differential forms aimed at the variational approach to Einstein's equations, including the differential forms development of the Hamiltonian approach to torsion gravity developed by Orlando Alvarez in his undergraduate thesis at Princeton.
