摘要

There is a hearsay that the PST approach to the covariant Lagrangian description of duality invariant theories is somewhat complicated. I will show, using an example of a chiral two-form field theory in six space-time dimensions, that it is actually natural and very simple. It directly stems from the Hamiltonian formulation of chiral-form theories.
