Random walks on networks with preferential cumulative damage: Generation of bias and aging
L. K. Eraso-Hernandez, A. P. Riascos, T. M. Michelitsch +1
In this paper, we explore the reduction of functionality in a complex system as a consequence of cumulative random damage and imperfect reparation, a phenomenon modeled as a dynami…
A markovian random walk model of epidemic spreading
Michael Bestehorn, Alejandro P. Riascos, Thomas M. Michelitsch +1
We analyze the dynamics of a population of independent random walkers on a graph and develop a simple model of epidemic spreading. We assume that each walker visits independently t…
Mean encounter times for multiple random walkers on networks
Alejandro P. Riascos, David P. Sanders
We introduce a general approach for the study of the collective dynamics of non-interacting random walkers on connected networks. We analyze the movement of independent (Markov…
Nonlocal biased random walks and fractional transport on directed networks
A. P. Riascos, T. M. Michelitsch, A. Pizarro-Medina
In this paper, we study nonlocal random walk strategies generated with the fractional Laplacian matrix of directed networks. We present a general approach to analyzing these strate…
