Critical properties of the Gauss model on a type of hierarchical lattice;

In this paper,using the renormalization-group transformation technique,the phase transition and critical properties of the modified Gauss model on a type of hierarchical lattice are studied,and its fixed points is K=b33 obtained.

Using the renormalization-group transformation method together with the cumulative expansion technique,the phase transition and critical properties of the S4 model on a type of hierarchical lattice were studied,and its fixed points and critical exponents were obtained.
