Boundedness of discounted tree sums

Elie Aïdékon, Yueyun Hu, Zhan Shi

Let $(V (u), u \in T)$ be a (supercritical) branching random walk and $(η_{u}, u \in T)$ be marks on the vertices of the tree, distributed in an i.i.d.\ fashion.…

The stochastic Jacobi flow

Elie Aïdékon, Yueyun Hu, Zhan Shi

The problem of conditioning on the occupation field was investigated for the Brownian motion in 1998 independently by Aldous [4] and Warren and Yor [34] and recently for the loop s…

Infinite disorder renormalization fixed point for the continuum random field Ising chain

Orphée Collin, Giambattista Giacomin, Yueyun Hu

We consider the continuum version of the random field Ising model in one dimension: this model arises naturally as weak disorder scaling limit of the original Ising model. Like for…

Convergence in law for the capacity of the range of a critical branching random walk

Tianyi Bai, Yueyun Hu

Let $R_{n}$ be the range of a critical branching random walk with $n$ particles on $Z^{d}$ , which is the set of sites visited by a random walk indexed by a critical Galton--Wat…

The sustainability probability for the critical Derrida-Retaux model

Xinxing Chen, Yueyun Hu, Zhan Shi

We are interested in the recursive model $(Y_{n}, n \geq 0)$ studied by Collet, Eckmann, Glaser and Martin [9] and by Derrida and Retaux [12]. We prove that at criticality, the prob…

Capacity of the range of branching random walks in low dimensions

Tianyi Bai, Yueyun Hu

Consider a branching random walk $(V_{u})_{u \in T^{I G W}}$ in $Z^{d}$ with the genealogy tree $T^{I G W}$ formed by a sequence of i.i.d. critical Galton-Watson t…
