Query: Algebraic Computation of the Hierarchical Renormalization Group Fixed
  Points and their $\epsilon$-Expansions   Nontrivial fixed points of the hierarchical renormalization group are
computed by numerically solving a system of quadratic equations for the
coupling constants. This approach avoids a fine tuning of relevant parameters.
We study the eigenvalues of the renormalization group transformation,
linearized around the non-trivial fixed points. The numerical results are
compared with $\epsilon$-expansion.
