comment Renormalization Group and Ising with d=1 and D=1
Thanks, i understand, but my question was: if i write the recursion relation $K'(K)$ and it inverse $K(K')$, one tends to decrease the coupling constant, and the other to increase. how to recognize what gives the correct flow of the coupling constant?

comment Statistical Mechanic
$F=-\frac{\log{Z_N}}{\beta}$, so $$\beta^2\frac{\partial F}{\partial\beta}=-\beta^2\frac{Z_N^{-1}\frac{\partial Z_N}{\partial\beta}\beta-\log{Z_N}}{\beta^2}=-\beta(-\langle U\rangle+F)=\beta TS=\frac{S}{k}$$
