摘要：We will compare the distribution of data within a genome with the distribution of data within a typical element of a symbolic extension of a topological dynamical system with positive residual entropy. Striking similarites are discovered (and some differences, too). This is a joint work with Professor Alejandro Maass (from University of Chile).
