Renewal Systems, Sharp-Eyed Snakes, and Shifts of Finite Type
Aimee S. A. Johnson, Kathleen Madden · American Mathematical Monthly · 2002
Johnson and Madden look at collections of bi-infinite strings of symbols that occur in several different areas of mathematics and ask whether these collections are the same in some sense. A dynamical systems property called entropy can be used to show that the shifts of finite type are not all conjugate to uniquely decipherable renewal systems.
