Abstract
We study boundary and finite-size effects in the Abelian sandpile model due to Bak, Tang and Wiesenfeld. In the case of half-plane
geometry,
the probability
of a unit height at the boundary, and at a
distance
r inside the sample is found for open and closed boundary
conditions. The leading asymptotic form of the correlation functions for the
unit heights,
, in the strip and half-plane geometries is obtained for different boundary conditions too. Our results confirm the hypothesis
that the unit height behaves like the local energy operator in the zero-component limit of the Potts model.
