A resolvent-type method for estimating time integrals of quadratic   fluctuations in weakly asymmetric exclusion
  We describe a resolvent-type method for estimating time integrals of time-dependent functionals of general right processes in equilibrium and apply this result in the case of weakly asymmetric one-dimensional simple exclusion showing a weak form of a replacement lemma for quadratic fluctuations.
