On the largest component of subcritical random hyperbolic graphs
Dieter Mitsche, Roland Diel
We consider the random hyperbolic graph model introduced by [KPK + 10] and then formalized by [GPP12]. We show that, in the subcritical case > 1, the size of the largest compon…

The heavy range of randomly biased walks on trees
Pierre Andreoletti, Roland Diel
We focus on recurrent random walks in random environment (RWRE) on Galton-Watson trees. The range of these walks, that is the number of sites visited at some fixed time, has been s…

Non parametric estimation for random walks in random environment
Roland Diel, Matthieu Lerasle
We consider a random walk in i.i.d. random environment with distribution on Z. The problem we are interested in is to provide an estimator of the cumulative distribution functi…
