Sudden extinction of a critical branching process in random environment

V. A. Vatutin V. Wachtel

Let $T$ be the extinction moment of a critical branching process $Z = (Z_{n}, n \geq 0)$ in a random environment specified by iid probability generating functions. We study the asympt…

Optimal local Hölder index for density states of superprocesses with $(1 + β)$ -branching mechanism

Klaus Fleischmann, Leonid Mytnik, Vitali Wachtel

For $0 < α \leq 2$ , a super- $α$ -stable motion $X$ in $R^{d}$ with branching of index $1 + β \in (1, 2)$ is considered. Fix arbitrary $t > 0$ . If $d < α / β$ , a dichotomy for the density fu…
