Note on the maximal jump size in a continuum model of directed first passage percolation
Ryoki Fukushima
In this note, we study the directed first passage percolation introduced in [F. Comets, R. Fukushima, S. Nakajima and N. Yoshida: Journal of Statistical Physics, 161-(3), 577-597 (…
Distribution of the random walk conditioned on survival among quenched Bernoulli obstacles
Jian Ding, Ryoki Fukushima, Rongfeng Sun +1
Place an obstacle with probability independently at each vertex of and consider a simple symmetric random walk that is killed upon hitting one of the obstacles.…
Quenched tail estimate for the random walk in random scenery and in random layered conductance II
Jean-Dominique Deuschel, Ryoki Fukushima
This is a continuation of our earlier work [Stochastic Processes and their Applications, 129(1), pp.102--128, 2019] on the random walk in random scenery and in random layered condu…
Biased random walk conditioned on survival among Bernoulli obstacles: subcritical phase
Jian Ding, Ryoki Fukushima, Rongfeng Sun +1
We consider a discrete time biased random walk conditioned to avoid Bernoulli obstacles on () up to time . This model is known to undergo a phase transi…
New high-dimensional examples of ballistic random walks in random environment
Ryoki Fukushima, Alejandro F. Ramírez
We give new criteria for ballistic behavior of random walks in random environment which are perturbations of the simple symmetric random walk on in dimensions $d\ge 4…
