Vertex reinforced branching random walks and generalized time-dependent Polya urns

Bruno Schapira

We consider a class of infinite critical tree-indexed random walks on , where the motion of particles is subject to vertex reinforcement. We mainly focus on the strong r…

On reversing the Simon-Lieb inequality in high-dimensional percolation

Romain Panis, Bruno Schapira

We study Bernoulli percolation on in dimensions . We prove that a classical consequence of the van den Berg-Kesten inequality, often referred to as the Simon-L…

Sharp bounds on the half-space two-point function for high-dimensional Bernoulli percolation

Romain Panis, Bruno Schapira

We consider Bernoulli percolation on with . We prove an up-to-constant estimate for the critical two-point function restricted to a half-space. This completes pr…

Derivative formula for capacities

Amine Asselah, Bruno Schapira, Perla Sousi

We obtain a derivative formula for various notions of capacity. Namely we identify the second order term in the asymptotic expansion of the capacity of a union of two sets, as thei…

Capacity in high dimensional percolation

Amine Asselah, Bruno Schapira, Perla Sousi

We introduce a notion of capacity for high dimensional critical percolation by showing that for any finite set , the suitably rescaled probability that the cluster of inters…

On the first and second largest components in the percolated Random Geometric Graph

Lyuben Lichev, Bas Lodewijks, Dieter Mitsche +1

The percolated random geometric graph has vertex set given by a Poisson Point Process in the square , and every pair of vertices at distance at most 1…
