We study the variance of the number of zeroes of a stationary Gaussian process on a long interval. We give a simple asymptotic description under mild mixing conditions. This allows us to characterise minimal and maximal growth. We show that...

We study random domino tilings of the Aztec diamond with a biased 2×2 periodic weight function and associate a linear flow on an elliptic curve to this model. Our main result is a double integral formula for the correlation kernel, in ...

We study a discrete-time Markov process on triangular arrays of matrices of size d≥1, driven by inverse Wishart random matrices. The components of the right edge evolve as multiplicative random walks on positive definite matrices with...

We study the dimer model on subgraphs of the square lattice in which vertices on a prescribed part of the boundary (the free boundary) are possibly unmatched. Each such unmatched vertex is called a monomer and contributes a fixed multiplica...

We prove limit laws for infinite horizon planar periodic Lorentz gases when, as time n tends to infinity, the scatterer size ρ may also tend to zero simultaneously at a sufficiently slow pace. In particular we obtain a non-standard Cen...
Global solutions of aggregation equations and other flows with random diffusion [0.03%]

Aggregation equations, such as the parabolic-elliptic Patlak-Keller-Segel model, are known to have an optimal threshold for global existence versus finite-time blow-up. In particular, if the diffusion is absent, then all smooth solutions wi...

We consider the imaginary Gaussian multiplicative chaos, i.e. the complex Wick exponential μ β : = : e i β Γ ( x ) : for a log-correlated Gaussian field Γ in d ≥ 1 dimensions. We prove a basic density resu...

The goal of this article is two-fold: in a first part, we prove Azuma-Hoeffding type concentration inequalities around the drift for the displacement of non-elementary random walks on hyperbolic spaces. For a proper hyperbolic space M, we o...
Approximation of martingale couplings on the line in the adapted weak topology [0.03%]

Our main result is to establish stability of martingale couplings: suppose that π is a martingale coupling with marginals μ , ν . Then, given approximating marginal measures μ ~ ≈ μ , ν ~ ≈ ν...

We prove the law of large numbers for the drift of random walks on the two-dimensional lamplighter group, under the assumption that the random walk has finite ( 2 + ϵ ) -moment. This result is in contrast with classical examples of a...
