title: Escape from noisy intermittent repellers
abstract: Intermittent or marginally stable repellers are commonly associated with a power law decay in the survival fraction. We demonstrate how the presence of weak additive noise alters the spectrum of the Perron-Frobenius operator significantly, giving rise to exponential decays even in systems that are otherwise regular. Implications for ballistic transport in marginally stable miscrostructures are also discussed.
