Comment on 'Reflecting and absorbing boundary conditions on the tail of the Laplacian random walk'

Abstract

In a recent letter Lyklema and Evertsz (see ibid., vol.19, p.895-900 (1986)) found a value of nu for the eta =1 Laplacian random walk which differs from the value the authors obtained for the diffusion-limited self-avoiding walk (DLSAW). They show that this results from different boundary conditions at the ends of these chains and not from a failing in our Monte Carlo studies of the DLSAW.
