On the speed of a one-dimensional random walk in a random environment perturbed by cookies of strength one
Elisabeth Bauernschubert
We consider a random walk in an i.i.d. random environment on Z that is perturbed by cookies of strength 1. The number of cookies per site is assumed to be i.i.d. Results on the spe…

Recurrence and transience of critical branching processes in random environment with immigration and an application to excited random walks
Elisabeth Bauernschubert
We establish recurrence and transience criteria for critical branching processes in random environment with immigration. These results are then applied to discuss recurrence and tr…

Perturbing transient Random Walk in a Random Environment with cookies of maximal strength
Elisabeth Bauernschubert
We consider a left-transient random walk in a random environment on Z that will be disturbed by cookies inducing a drift to the right of strength 1. The number of cookies per site…
