A Note on the Decay of Correlations Under Delta-Pinning
(30K, LATeX 2e)
ABSTRACT. We prove that for a class of massless $\nabla\phi$ interface models on $\Ztwo$
an introduction of an arbitrary small pinning self-potential leads to
exponential decay of correlation, or, in other words, to creation of mass.
