摘要
We show that every shift of finite type X with positive entropy has proper subshifts of finite type with entropy strictly smaller than the entropy of X, but with entropy arbitrarily close to the entropy of X. Consequently, X contains an infinite chain of subshifts of finite type which is strictly decreasing in entropy.
