Query: Self-dual forms: Action, Hamiltonian and Compactification   It has been shown that, by adding an extra free field that decouples from the
dynamics, one can construct actions for interacting 2n-form fields with
self-dual field strengths in 4n+2 dimensions. In this paper we analyze
canonical formulation of these theories, and show that the resulting
Hamiltonian reduces to the sum of two Hamiltonians with independent degrees of
freedom. One of them is free and has no physical consequence, while the other
contains the physical degrees of freedom with the desired interactions. For the
special cases of chiral scalars in two dimensions and chiral two form fields in
six dimensions, we discuss compactification of these theories respectively on a
circle and a two dimensional torus, and show that we recover the expected
properties of these systems, including S-duality invariance in four dimensions.
