  "abstract": "The block counting process and the fixation line of the Bolthausen-Sznitman coalescent are analyzed. Spectral decompositions for their generators and transition probabilities are provided leading to explicit expressions for functionals such as hitting probabilities and absorption times. It is furthermore shown that the block counting process and the fixation line of the Bolthausen-Sznitman $n$-coalescent, properly scaled, converge in the Skorohod topology to the Mittag-Leffler process and Neveu's continuous-state branching process respectively as the sample size $n$ tends to infinity. Strong relations to Siegmund duality and to Mehler semigroups and self-decomposability are pointed out.",
