Abstract
We study probabilities of large extremes of the storage process Y(t) = sup σ≥t (X(σ) - X(t) - c(σ - t)), where X(t) is the fractional Brownian motion. We derive asymptotic behavior of the maximum tail distribution for the process on fixed or slowly increased intervals by a reduction the problem to a large extremes problem for a Gaussian field.
