Lifting linear preferential attachment trees yields the arcsine coalescent

Helmut H. Pitters

We consider linear preferential attachment trees which are specific scale-free trees also known as (random) plane-oriented recursive trees. Starting with a linear preferential atta…

The hydrodynamic limit of beta coalescents that come down from infinity

Luke Miller, Helmut H. Pitters

We quantify the manner in which the beta coalescent $Π = {Π (t), t \geq 0},$ with parameters $a \in (0, 1),$ $b > 0,$ comes down from infinity. Approximating $Π$ by its restriction $Π^…
