Molchan, George Survival exponents for fractional Brownian motion with multivariate time. (English) Zbl 1355.60053 ALEA, Lat. Am. J. Probab. Math. Stat. 14, No. 1, 1-7 (2017). Summary: Fractional Brownian motion of index \(0 < H < 1\), \(H\)-FBM, with \(d\)-dimensional time is considered in a spherical domain that contains 0 at its boundary. The main result: the log-asymptotics of the probability that H-FBM does not exceed a fixed positive level is \((H-d + o(1))\log T\), where \(T \gg 1\) is the radius of the domain.
