Abstract

For certain subordinators (Xt)t≥0 it is shown that the process (-tlogXts)s>0 tends to an extremal process (ηîs)s>0 in the sense of convergence of the finite dimensional distributions. Additionally it is also shown that ((-tlog X ts))s≥0 converges weakly to (Z,ns) s≥0 in D[0,∞), the space of càdl̀ag functions equipped with Skorohod's J1 metric.
