Positively and negatively excited random walks on integers, with branching processes
Positively and negatively excited random walks on integers, with branching processes
We consider excited random walks on the integers with a bounded number of i.i.d. cookies per site which may induce drifts both to the left and to the right. We extend the criteria for recurrence and transience by M. Zerner and for positivity of speed by A.-L. Basdevant and A. …
