摘要：
A fermionic version of Dyson's hierarchical model is defined. An exact renormalization group transformation is given as a rational transformation of two-dimensional parameter space. Two branches of nontrivial fixed points are described, one of which bifurcates from the trivial ''Gaussian'' branch. The existence of the thermodynamic limit for these branches of fixed points is investigated.
