Local Cohomology in Field Theory (with Applications to the Einstein Equations)
Second Mexican School on Gravitation and Mathematical Physics
This is an introductory survey of the theory of p-form conservation laws in field theory. It is based upon a series of lectures given at the Second Mexican School on Gravitation and Mathematical Physics held in Tlaxcala, Mexico from December 1–7, 1996.
