Two-Dimensional Moran Model: Final Altitude and Number of Resets

In this paper, we consider a two-dimension symmetric random walk with reset. We give, in the first part, some results about the distribution of every component. In the second part, we give some results about the final altitude Z_n. Finally, we analyse the statistical properties of  N_n^X, the number of resets (the number of returns to state 1 after n steps) of the first component of the random walk. As a principal tool in these studies, we use the probability generating function

In this article, we consider several models of random walks in one or several

dimensions, additionally allowing, at any unit of time, a reset (or “catastrophe”) of

the walk…
