Title: Hyperscaling in the broken symmetry phase of Dyson's hierarchical model

Abstract

We use polynomial truncations of the Fourier transform of the local measure to calculate the connected q-point functions of Dyson's hierarchical model in the broken symmetry phase. We show that accurate values of the connected one-, two-, and three-point functions can be obtained at large volume and in a limited range of constant external field coupled linearly to the field variable. We introduce a new method to obtain the correct infinite volume and zero external field extrapolations. We extract the leading critical exponents and show that they obey the scaling and hyperscaling relations with an accuracy ranging from 10{sup -5} to 5x10{sup -3}. We briefly discuss how to improve the method of calculation. (c) 2000 The American Physical Society.
