A $K$-theoretic invariant for dynamical systems
A $K$-theoretic invariant for dynamical systems
Let (X, T) be a zero-dimensional dynamical system.We consider the quotient group G = C(X, Z)/B(X, T), where C(X, Z) is the group of continuous integer-valued functions on X and B(X, T) is the subgroup of functions of the form f -f o T .We show that if (X, T) …
