| contents | We establish some conditions under which $\text{GL}(d,\mathbb{R})$-valued cocycles over a subshift of finite type, equipped with an equilibrium state, exhibit exponential asymptotics for the spectral radius. Specifically, we show that the exponential growth rate of the spectral radius converges to the top Lyapunov exponent of the cocycle. This result provides a partial answer to a question posed by Aoun and Sert in their paper "Law of large numbers for the spectral radius of random matrix products" (2021). Our approach relies on large deviation estimates for linear cocycles, which may be of independent interest. |
