Abstract:

We discuss the stability and the expansivity of the tent map $f:[0,1]\to [0,1]$ defined by $f(x)=2\min \{x,1-x\}$ for $0\leq x\leq 1$. Indeed, we show that $f$ is neither topologically stable nor orbit shift topologically stable nor countably-expansive but is cw-topologically stable, orbit shift cw-expansive, and orbit shift $\alpha$-persistent.
