摘要：In this talk, I will present a study on the group extensions for topologically mixing random shifts of finite type and consider the natural comparison of relative Gurevič entropies between random group G and G^{a,b}=G/[G,G] extensions. We show that the relative Gurevič entropy of random group G extensions is equal to the relative Gurevic entropy of random group G^{a,b} extensions if and only if G is amenable. This is a joint work with K.Yang, Z.Lin and X. Zhou.
