Noncolliding Macdonald walks with an absorbing wall

  title={Noncolliding Macdonald walks with an absorbing wall},
  author={Leonid A. Petrov},
The branching rule is one of the most fundamental properties of the Macdonald symmetric polynomials. It expresses a Macdonald polynomial as a nonnegative linear combination of Macdonald polynomials with smaller number of variables. Taking a limit of the branching rule under the principal specialization when the number of variables goes to infinity, we obtain a Markov chain of m noncolliding particles with negative drift and an absorbing wall at zero. The chain depends on the Macdonald parameters…

We study the $\beta $ analogue of the nonintersecting Poisson random walks. We derive a stochastic differential equation of the Stieltjes transform of the empirical measure process, which can be
Markov processes of infinitely many nonintersecting random walks
Consider an N-dimensional Markov chain obtained from N one-dimensional random walks by Doob h-transform with the q-Vandermonde determinant. We prove that as N becomes large, these Markov chains
Non-Colliding Random Walks, Tandem Queues, and DiscreteOrthogonal Polynomial Ensembles
We show that the function $h(x)=\prod_{i < j}(x_j-x_i)$ is harmonic for any random walk in $R^k$ with exchangeable increments, provided the required moments exist. For the subclass of random walks
Universality of local spectral statistics of random matrices
The Wigner-Gaudin-Mehta-Dyson conjecture asserts that the local eigenvalue statistics of large random matrices exhibit universal behavior depending only on the symmetry class of the matrix ensemble.
Orthogonal polynomial ensembles in probability theory
We survey a number of models from physics, statistical mechanics, probability theory and combinatorics, which are each described in terms of an {it orthogonal polynomial ensemble}. The most prominent
Universality of local statistics for noncolliding random walks
We consider the $N$-particle noncolliding Bernoulli random walk --- a discrete time Markov process in $\mathbb{Z}^{N}$ obtained from a collection of $N$ independent simple random walks with steps
Random Skew Plane Partitions with a Piecewise Periodic Back Wall
Random skew plane partitions of large size distributed according to an appropriately scaled Schur process develop limit shapes. In the present work, we consider the limit of large random skew plane
A Brownian‐Motion Model for the Eigenvalues of a Random Matrix
A new type of Coulomb gas is defined, consisting of n point charges executing Brownian motions under the influence of their mutual electrostatic repulsions. It is proved that this gas gives an exact
Multilevel Dyson Brownian motions via Jack polynomials
We introduce multilevel versions of Dyson Brownian motions of arbitrary parameter $$\beta >0$$β>0, generalizing the interlacing reflected Brownian motions of Warren for $$\beta =2$$β=2. Such
Introduction to Random Matrices
Here I = S j (a2j 1,a2j) andI(y) is the characteristic function of the set I. In the Gaussian Unitary Ensemble (GUE) the probability that no eigenvalues lie in I is equal to �(a). Also �(a) is a
