Let $A(x,n)$ be the cocycle over $f$, where $f$ is a measure-preserving transformation on a probability space $X$. Is the largest Lyapunov exponent always given by:
$\lim_{n\to +\infty} \log ||A(x,n)||$$\lim_{n\to +\infty} \log \|A(x,n)\|$?
Since the above limit can be bounded from above by $\int_X\log ||A||$$\int_X\log \|A\|$, can one give an example of the cocycle where the above inequality is strict? Tnx!
