摘要:We consider the Metropolis biased card shuffling (also called the multispecies ASEP on a finite interval or the random Metropolis scan). Its convergence to stationarity was believed to exhibit a total -variation cutoff, and that was proved a few years ago by Labbe and Lacoin (Ann. Probab. 47 (2019) 1541-1586). In this paper, we prove that (for N cards) the cutoff window is in the order of N1/3, and the cutoff profile is given by the Tracy-Widom GOE distribution function. This confirms a conjec...

摘要:We establish central limit theorems for the volumes of intersections of Bpn (the unit ball of in p) with uniform random subspaces of codimension d for fixed d and n -> infinity. As a corollary we obtain higher-order approximations for expected volumes, refining previous results by Koldobsky and Lifschitz and approximations obtained from the Eldan-Klartag version of CLT for convex bodies. We also obtain a central limit theorem for the Minkowski functional of the intersection body of Bnp, evalua...

摘要:Consider the Schrodinger operator L-V = - Delta + V on R-d , where V : R-d -> [0 , infinity) is a nonnegative and locally bounded potential on R-d so that for all x is an element of R-d with | x | >= 1, c(1)g( | x | ) <= V (x) <= c(2)g( | x | ) with some constants c 1 , c(2) > 0 and a nondecreasing and strictly positive function g : [0,infinity) -> [1 ,+infinity ) that satisfies g(2r) <= c(0)g(r) for all r > 0 and lim(r ->infinity )g(r) = infinity . We establish global in time and qualitativel...

摘要:We show that the Weil-Petersson probability that a random surface has first eigenvalue of the Laplacian less than 3/16-epsilon goes to zero as the genus goes to infinity.

摘要:Consider a system of Brownian particles on the real line where each pair of particles coalesces at a certain rate according to their intersection local time. Assume that there are infinitely many initial particles in the system. We give a necessary and sufficient condition for the number of particles to come down from infinity. We also identify the rate of this coming down from infinity for different initial configurations.

摘要:We consider the model of Brownian motion indexed by the Brownian tree, which has appeared in a variety of different contexts in probability, statistical physics and combinatorics. For this model the total occupation measure is known to have a continuously differentiable density (l(x))(x is an element of R), and we write (l(x))(x is an element of R )for its derivative. Although the process (l(x))(x >= 0) is not Markov, we prove that the pair(l(x), l(x))(x >= 0 )is a time-homogeneous Markov proc...

摘要:We consider a branching Brownian motion in Rd with d >= 1 in which the position X(u) t is an element of Rd of a particle u at time t can be encoded by its direction theta(u) t is an element of Sd-1 and its distance R(u) t to 0. We prove that the extremal point process Sigma delta(theta(u) t,Rt(u)-m(d) t ) (where the sum is over all particles alive at time t and m(d) t is an explicit centering term) converges in distribution to a randomly shifted, decorated Poisson point process on Sd-1 x R. Mo...

摘要:The Discrete Gaussian model is the lattice Gaussian free field conditioned to be integer-valued. In two dimensions and at sufficiently high temperature, we show that the scaling limit of the infinite-volume gradient Gibbs state with zero mean is a multiple of the Gaussian free field. This article is the second in a series on the Discrete Gaussian model, extending the methods of the first paper by the analysis of general external fields (rather than macroscopic test functions on the torus). As ...

摘要:We prove a shape theorem for internal diffusion limited aggregation on mated-CRT maps, a family of random planar maps which approximate Liouville quantum gravity (LQG) surfaces. The limit is a LQG harmonic ball, which we constructed in a companion paper. We also prove an analogous result for the divisible sandpile.

摘要:We study the asymptotic behaviour of random integer partitions under a new probability law that we introduce, the Plancherel-Hurwitz measure. This distribution, which has a natural definition in terms of Young tableaux, is a deformation of the classical Plancherel measure, which appears naturally in the context of Hurwitz numbers, enumerating certain transposition factorisations in symmetric groups. We study a regime in which the number of factors in the underlying factorisations grows linearl...
