| Descricão e Informacões Adicionais | We use a decimation procedure in order to obtain the dynamical renormalization group trans-formation (RGT)properties of random walk distribution in a 1+1 lattice.We obtain an equation similar to the Chapman Kolmogorov equation.First we show the existence of invariants of the RGT,and that the Tsallis distribution Rq (x )=[1+b (q -1)x 2 ]1 =(1 -q (q 1) is a quasi-invariant of the RGT.We obtain the map q =f (q from the RGT and show that this map has two fixed points:q =1,attractor,and q =2,repellor,which are the Gaussian and the Lorentzian, respectively.Finally we use those concepts to show that the nonadditivity of the Tsallis entropy needs to be reviewed. |
