Description
We discuss properties of actions which are invariant under
smooth deformations of the lattice fields, which are
restricted to a subspace of phase space. In particular
we comment on the continuum limit of such
actions and show how to directly measure the free energy.
We also investigate possible applications to finite
density systems.
