Abstract: | Correction to scaling effects for the directed branched polymer (lattice animal) problem are calculated both from the field theoretic model due to Day and Lubensky (dynamics at the Yang-Lee edge singularity) and enumeration data. The universal correction to scaling exponent for the number of distinct animal configurations is estimated by numerical methods and field theoretic renormalization group results ( =7–d expansion) extrapolated to exact results ford=2 andd=3; estimates of nonuniversal amplitudes are included. |
