Optimal Stopping with Rank-Dependent Loss

Alexander V. Gnedin

For $τ$ a stopping rule adapted to a sequence of $n$ iid observations, we define the loss to be $\ex [ q(R_τ)]$, where $R_{j}$ is the rank of the $j$ th observation, and $q$ is a nond…

On the number of collisions in $Λ$ -coalescents

Alexander Gnedin, Yuri Yakubovich

We examine the total number of collisions $C_{n}$ in the $Λ$ -coalescent process which starts with $n$ particles. A linear growth and a stable limit law for $C_{n}$ are shown under the…
