Zero temperature limit for the Brownian directed polymer among Poissonian disasters
Ryoki Fukushima, Stefan Junk
We study a continuum model of directed polymer in random environment. The law of the polymer is defined as the Brownian motion conditioned to survive among space-time Poissonian di…
Random conductance models with stable-like jumps: heat kernel estimates and Harnack inequalities
Xin Chen, Takashi Kumagai, Jian Wang
We establish two-sided heat kernel estimates for random conductance models with non-uniformly elliptic (possibly degenerate) stable-like jumps on graphs. These are long range count…
Slowdown estimates for one-dimensional random walks in random environment with holding times
Amir Dembo, Ryoki Fukushima, Naoki Kubota
We consider a one dimensional random walk in random environment that is uniformly biased to one direction. In addition to the transition probability, the jump rate of the random wa…
Long range random walks and associated geometries on groups of polynomial growth
Zhen-Qing Chen, Takashi Kumagai, Laurent Saloff-Coste +2
In the context of countable groups of polynomial volume growth, we consider a large class of random walks that are allowed to take long jumps along multiple subgroups according to…
Geometry of the random walk range conditioned on survival among Bernoulli obstacles
Jian Ding, Ryoki Fukushima, Rongfeng Sun +1
We consider a discrete time simple symmetric random walk among Bernoulli obstacles on , , where the walk is killed when it hits an obstacle. It is known that…
Large deviations for intersection measures of some Markov processes
Takahiro Mori
Consider an intersection measure of independent (possibly different) -symmetric Hunt processes up to time in a metric measure space with a Ra…
Random Conductance Models with Stable-like Jumps: Quenched Invariance Principle
Xin Chen, Takashi Kumagai, Jian Wang
We study the quenched invariance principle for random conductance models with long range jumps on , where the transition probability from to is, on average, comparabl…
