Description
We define a finite size renormalization scheme for
$\phi^4$ theory which in the thermodynamic limit
reduces to the standard scheme used in the
broken phase. We use it to re-investigate
the question of triviality for the four dimensional
infinite bare coupling (Ising) limit. The relevant
observables all rely on two-point functions and
are very suitable for a precise estimation
with the worm algorithm.
