The Lanczos potential as a spin-2 field
Daniel Cartin
Abstract
The Lanczos potential Labc acts as a tensor potential for the spin-2 field strength Wabcd in an role similar to that of the vector potential Aa for the Maxwell tensor Fab. After some general considerations inspired by the example of electromagnetism, we consider the linear spin-2 theory and a Born-Infeld type action in terms of Labc.
