Definition
Let $\struct {X_\mathbf A ^+, \sigma}$ be a one-sided shift of finite type.
Let $F_\theta^+$ be the space of Lipschitz functions on $X_\mathbf A ^+$.
Let $f \in F_\theta ^+$ be a real-valued function.
Let $\LL _f : F_\theta^+ \to F_\theta^+$ be the Ruelle-Perron-Frobenius Operator.
Then $\LL _f$ is normalized if and only if:
- $\LL _f 1 = 1$
