Popis: | A one-dimensional shift of finite type (X,Z) with entropy at least logn factors onto the full n-shift. The factor map is constructed by exploiting the fact that X, or a subshift of X, is conjugate to a shift of finite type in which every symbol can be followed by at least n symbols. We will investigate analogous statements for higherdimensional shifts of finite type. We will also show that for a certain class of mixing higher-dimensional shifts of finite type, sufficient entropy implies that (X,Z ) is finitely equivalent to a shift of finite type that maps onto the full n-shift. |
