3D crystal: how flat its flat facets are?
(322K, Postscript)

ABSTRACT.  We investigate the hypothesis that the (random) crystal of the 
$(-)$-phase inside the $(+)$-phase of the 3D canonical Ising 
model has flat facets. We argue that it might need to be weakened, 
due to the possibility of formation of extra monolayer on a facet. 
We then prove this weaker hypothesis for the Solid-On-Solid model.
